0 -> Hey, what's up guys, Anuj here.

0.851 -> And in today's video, we're going to talk about how you should practice coding

4.286 -> the best, ultimate way - the ultimate guide to practice coding

7.615 -> we're going to discuss it in today's video.

9.571 -> When we're practicing coding, we know that

11.658 -> practicing is a very important part of any programming journey

15.358 -> But while you're practicing, then I do get doubts

18.03 -> even when I was in the phase of my practicing journey of programming

22.714 -> then it used to happen which I'll share with you all

25.714 -> that we visit different websites and spend hours

29.229 -> and even after spending hours, we don't get the desired output

32.185 -> at the end of the day.

33.4 -> We were practicing questions but still, we don't get a sense of satisfaction

37.131 -> we still have a sense of doubt that

38.971 -> if this question arises again, then we might not be able to do it

41.5 -> We're going to practice questions but we're not able to solve it

44.787 -> We're not able to understand the logic.

46.3 -> And it happens, if you'll know what's the root cause

49.558 -> then it comes out to be that you all are not practicing properly

53.115 -> I have faced this myself

54.171 -> alright!

54.734 -> I used to face this earlier but now the scenario has changed

57.137 -> But now the situation is that, if I've an interview tomorrow

59.943 -> still, I've enough confidence

62.069 -> that's okay, it's a coding interview. I'll be able to pass it.

65.814 -> Practice is enough and I've got the knowledge about how to practice

70.032 -> So, today I'm going to guide you properly and tell you about an amazing resource

74.077 -> that is how you should practice if you need to do it topic wise

78.286 -> if you need to practice company-wise, how you need to move forward

82.271 -> and the best way

83.886 -> I'm going to share the best resource with you in today's video.

86.807 -> The resource that I'm talking about - you already know about it

89.565 -> it's very famous

90.587 -> wherever you're in engineering or related anywhere in the computer programming

94.144 -> then you must know about this website

96.515 -> you might have guessed it till now

97.944 -> yes, it is Geeks for geeks.

99.543 -> And you all know it because this is one of the best websites.

102.6 -> That is why you know it.

103.671 -> Whenever you search for anything, you find Geeks for Geeks.

106.057 -> But, you might say that we were talking about practice.

108.234 -> It's that whenever we need to find any article

110.9 -> we search google and find Geeks for Geeks.

113.871 -> Can we even practice on Geeks for Geeks?

115.532 -> Yes, we can.

116.386 -> Geeks for Geeks has improved the practice platform a lot.

119.617 -> and today we'll be talking about the practice on Geeks for Geeks.

122.943 -> So, whenever you practice it's important to keep 3 things in mind.

127.315 -> Let's talk about those 3 things first then we'll

129.471 -> talk about the practice of Geeks for geeks

132.087 -> alright!

132.658 -> And how you all should practice in the best way!

135.329 -> We'll talk about that.

136.1 -> First of all, we need to keep 3 things in mind.

138.072 -> Firstly, whenever you're going to practice

140.579 -> the concept that you're practicing your question upon

144.472 -> you should have enough knowledge of it.

146.423 -> You should know the basics - its theory

148.771 -> you should have seen some easily solved questions as well

152.372 -> earlier itself.

153.114 -> Then only you've to move inside.

154.657 -> You know that - you need to study binary search

156.215 -> You've to study the binary search tree

157.5 -> until I practice for the Binary search tree, then I won't be able to do its concept

163.275 -> If I went only after studying theory in the interview

166.072 -> then I'll make mistake somewhere

168.463 -> I'll make mistake somewhere in the base cases.

170.271 -> If you don't trust then you can try it for yourself

172.364 -> the code of Delete, node and binary search tree

174.287 -> if you'll try to do it then, the majority of people will be making a mistake

177.287 -> somewhere or the other

178.006 -> alright!

178.886 -> So, practice is very important in that case.

181.243 -> But, before practice, you should know what a binary search tree is.

184.857 -> you won't directly jump into the question that is why

187.325 -> you should know the theory. This was the 1st point.

189.871 -> The second point is that you don't need to directly do medium or hard questions

193.945 -> you should do easy questions first, then medium

197.072 -> then after that do the hard questions

198.757 -> Alright!

199.343 -> With this, you might have done enough easy questions

202.301 -> then you might not even know when you'll be able to do medium questions

206.977 -> and when you would have done enough medium questions

210.064 -> then you would be able to do hard questions as well

212.757 -> alright!

213.5 -> there isn't any fine line, which needs to be crossed by a step

217.801 -> It's not that!

218.8 -> it's a very vague line

219.871 -> you'll not even know when you'll move out of the easy territory to the medium

224.114 -> and I'm telling you this by a lot of experience.

226.388 -> And the third point is to stay consistent.

228.315 -> don't ever let the consistency break.

230.657 -> If you need to stay confident that I've got an interview tomorrow and

232.744 -> I'll crack the interview. You need this type of confidence then

235.372 -> never let the consistency break.

237.586 -> My consistency hasn't been broken until now.

239.334 -> Now, its been 2-3 years since I left college

242.9 -> and I've left companies for a long time but still

245.687 -> I don't let the consistency break.

248.057 -> I've one or the other questions in mind

250.643 -> Sometimes while I'm practicing with my brother or

252.872 -> sometimes I come across a good question and I'm thinking about it.

255.988 -> So, you shouldn't let this consistency break and need to practice as well.

259.029 -> You need to type on the keyboard as well.

261.027 -> It doesn't happen only by thinking.

263.211 -> if you've thought about it in mind and when actual implementation comes

266.028 -> then you might not be able to do it.

267.357 -> So, these 3 things need to be kept in mind.

269.371 -> And all of these 3 things are fulfilled from the Geeks for Geeks website.

274.143 -> Now, talking about how to practice Geeks for Geeks, so

276.657 -> if you'll open Geeks for Geeks - GeeksforGeeks.org

279.686 -> then you'll say that there are so many things inside it.

284.257 -> that we're not able to understand from where we're going to start

286.657 -> and where to end

287.372 -> So, what you're thinking is correct because

290.147 -> you can see here, that there are a lot of things

292.257 -> Data structures, algorithms, interview preparation

293.915 -> they've divided into a segment because

295.972 -> it has a breadth of knowledge inside it

298.286 -> The breadth of knowledge is stored in it.

300.3 -> So, it's important for you to choose your path

303.387 -> but, today I'm going to show you all

305.087 -> the second variant of Geeks for geeks

307.157 -> on the second page of Geeks for geeks

308.587 -> where everything is very streamlined

311.716 -> and you should practice in this way only

315.314 -> So this is www.GeeksforGeeks.org

317.5 -> we don't need to go in it. Instead, we've to visit practice.GeeksforGeeks.org

321.2 -> and for that, if you click on courses

323.786 -> then you'll come to practice.GeeksforGeeks.org

326.429 -> this is practice.GeeksforGeeks.org

328.714 -> and this is their homepage

330.671 -> Bookmark this. I've already done it.

333.4 -> By that, you can reach it quickly.

335.757 -> So, this is the page and you can see that there aren't many options on it.

339.372 -> It's very finite and we're going to talk about

342.526 -> majorly 2 things with you.

345.8 -> firstly, the problems part and secondly, the POTD part

349.165 -> First let's talk about, problems.

350.358 -> POTD means the problem of the day.

352.157 -> they've made it amazing and the 3 things that I've told you

354.971 -> that you'll have to start learning. You know that theory on GeeksforGeeks

359.323 -> then after that you've to practice questions on it - easy, medium, hard.

363.171 -> If you've to practice company-wise, then also you can do it very easily

365.6 -> and then, finally being consistent

368.043 -> GeeksforGeeks also helps in it so

370.112 -> that is why we're talking about it today

371.882 -> Alright!

372.271 -> So, let's start with if we visit the problems section then here we'll

375.464 -> see that there are a lot of problems

377.314 -> Each problem is very nice---- Now UI has changed a lot

381.029 -> when I was in college, I remember there wasn't this nice UI

384.798 -> and there was a lot of confusion. It used to vary.

388.114 -> So, now in the matter of UI it's been a lot better.

390.657 -> and now you all have multiple features provided in it.

393.557 -> First of all, problem type.

394.615 -> If you want to solve the full problem, means you want to write the entire code yourself

398.2 -> entirely, from class until function.

400.287 -> You want to write entirely yourself.

401.56 -> Then you can go on to full problems.

403.343 -> Otherwise, you need to solve only one function that I'm observing these days

407.215 -> coding contests of multiple companies

410.486 -> they directly give functional questions/problems in coding tests so

415.044 -> you can directly practice that

417.157 -> alright!

417.757 -> And then, you can bookmark the problems, then

419.757 -> you can set the difficulty level

421.171 -> like School, medium, easy, hard

424.029 -> and then you can sort these questions on the basis of submissions

427.386 -> which has the large no. of submissions, which has most no. of queries

429.601 -> which is the newest question,

431.398 -> so these features were already in it

433.192 -> then you can practice company-wise if a company is visiting

436.472 -> then you can practice accordingly

438.486 -> Now, let me show from inside how the UI has transformed and changed everything

444.014 -> Alright!

444.9 -> Okay!

445.614 -> the question is, for example, check for BST

448.129 -> inside it, if you've not opened GeeksforGeeks for many days then

452.076 -> it has reformed very much

453.76 -> the entire system

455.371 -> Now, editorial, submission, and doubts support have different sections each

462.086 -> UI has been reformed. One more thing

463.757 -> Earlier, I remember, the test cases that were there

466.544 -> they were like, we could solve 2-3 test cases and

470.349 -> it might be that our code won't work on multiple test cases

473.329 -> Now, it has been fixed as well.

474.614 -> Multiple test cases have been put in it for you

477.157 -> Alright!

477.774 -> And, now it's not that you solved a question

481 -> and if its takes 5-6 seconds for the submission, it'll still be accepted

485.015 -> earlier, it happened.

486.358 -> Now, it isn't that.

487.264 -> And if you want to be able to solve it, then you'll get 2 points

489.739 -> Alright!

490.386 -> You collect these points, through which your ranking increases

494.771 -> your monthly ranking increases, your overall ranking

498.015 -> college-wise ranking increases, you tell that you're from this college then

502.186 -> it also tells your ranking in the college

504.079 -> then you can see that in your college, this person is above you

506.687 -> this person is below you

507.969 -> Alright!

508.479 -> So, it's very good in that case.

510.798 -> Alright!

511.261 -> Apart from that if you're not able to solve the question then directly

515.805 -> you can move on to the editorial of GeekforGeeks

518.243 -> you know that if you want to search for any question

520.618 -> in GeeksforGeeks, you get its solution very quickly

524.414 -> apart from that, you can see your past submissions

527.02 -> that how did I do earlier and now how am I going to do it

531.519 -> so this was its overall interface. It's a very defined interface.

535.857 -> Again, if we talk about it then you've to first start with easy

539.218 -> then medium, then hard. So first, we'll go to easy problems

541.855 -> Alright!

542.287 -> Let's remove the company tags.

543.671 -> If you want to practice topic-wise, which you should

547.101 -> so first of all, suppose we went to mathematics

549.773 -> then we've to do only easy questions of mathematics

552.154 -> Once you've done enough easy questions

554.186 -> when will we know to move from easy to medium

556.53 -> once you've done enough easy questions and now you feel that

558.858 -> this question has been solved in a blink

560.9 -> then you'll feel the inner sense

563.843 -> you feel that slowly

565.814 -> when you feel that this question can be solved in a blink

568.389 -> then you'll yourself shift to medium questions

571.493 -> then you'll start doing medium questions and when you'll start to feel

574.095 -> medium questions can be solved in a blink, its logic is easy

577.372 -> then you've to move onto hard

579.087 -> Okay!

579.437 -> So in this way you've to practice easy, medium and hard questions here

582.371 -> there are multiple topics, as you can see here

585.529 -> Right!

585.929 -> These are all of the topics and it's important to know about every topic

589.272 -> if you want to crack interviews

591.729 -> so visit each of the topics one-by-one

594.114 -> do easy questions, then medium, then hard

597.586 -> if a company is visiting and wants to know what type of questions

601.243 -> is generally asked in this company

602.557 -> it's still a better website

603.915 -> you just have to

606.5 -> select the company tags

607.672 -> suppose in amazon

609.814 -> I'll get all of the mathematical questions over here

613.284 -> Okay!

613.787 -> al the easy ones

614.767 -> if you want to see medium questions then you can search it like this

618.13 -> so in this case I felt the UI was better

621.282 -> and you can see all of it above that what all filters have you applied

624.943 -> and you can even change these filters

626.965 -> now let's talk about the second thing

628.586 -> by which GeeksforGeeks is helping to improve your consistency in practice

632.33 -> which is POTD

633.971 -> the problem of the Day

635.286 -> I felt that this concept was amazing.

636.996 -> Basically, you can solve daily one question over here, right!

640.346 -> And right now everyone might be able to see it.

643.044 -> Largest rectangle of 1s with swapping of columns allowed

646.457 -> okay! So, its a very good question.

647.683 -> Its a hard question. Medium and hard questions are given over here

649.703 -> so this is a hard question.

651.6 -> let's think about how the question will be solved.

655.286 -> So basically, you're given an array in which there are 0s and 1s

658.371 -> so, actually, I've done this question in which swapping wasn't allowed

661.986 -> but

663.5 -> there are rectangles of 0s and 1s and you've to tell the maximum rectangle so

666.33 -> for that. You'll do maximum area in a histogram

669.872 -> then you'll move downward row by row

671.657 -> here, swapping of columns is allowed so you can do one thing

675.571 -> that you go on sorting

678.529 -> basically, this can be one way.

680.229 -> That goes on to each row and sort and then since swapping is allowed

684.544 -> then you can keep the higher rectangles on one side.

688.658 -> and you can bring it from that, what can be the maximum area, right!

692.299 -> because you can find the maximum are from it.

694.222 -> from there you can find time complexity if there are R rows and C columns

698.586 -> O(r)

700.057 -> times c

701.506 -> times log c because log would be there in sorting

705.343 -> Right!

705.837 -> So, basically, why am I discussing questions?

709.229 -> Alright!

710.043 -> So, in this way its the problem of the day.

711.391 -> The main thing of the practice of the day is

713.444 -> when you're practicing in it, you get coins

716.252 -> alright!

716.571 -> And by using those coins you can.....

720.255 -> And one more thing

720.939 -> that the question is discussed daily on the Youtube channel

723.978 -> so, if you're stuck, you're not able to understand it then

727.257 -> you can visit their youtube channel how is it going to be solved

730.477 -> Right!

731.057 -> So, I found this thing very cool.

733.271 -> Here it is.

733.557 -> POTD Handbook

734.757 -> So when you visit here, then you get a Geekbit.

737.086 -> These are basically coins and by using them you can

740.171 -> buy many merchandise and amazon voucher coupons

744.472 -> so I've a younger brother, who has actually bought it

747.603 -> right!

748.071 -> So, I find this thing very interesting.

751.371 -> So, definitely its worth checking out and

753.843 -> you'll be practicing daily-daily it won't let your consistency break

757.401 -> basically, it'll improve your consistency slowly if you solve a question daily

761.951 -> apart from that you directly get its submission that

765.258 -> how actually the person thinking about this question

767.771 -> so, that is also very interesting.

769.457 -> Alright!

770.03 -> So this was it. And apart from that basically, there are other things like

773.614 -> they've given courses

774.637 -> So, GeeksforGeeks have its own courses.

777.043 -> You can access those courses.

779.457 -> There is a section they have added called get hired.

781.587 -> Where multiple companies are hiring through GeeksforGeeks

784.571 -> apart from that, there are other events I think

787.371 -> these are all the events where some people come

790.871 -> so basically, these are the events but the most important thing was

794.075 -> that I wanted to tell you was that yes, you can practice on GeeksforGeeks

797.486 -> there is a lot of knowledge in GeeksforGeeks

799.763 -> you might know that, whenever you search for something

802.058 -> the link for GeekforGeeks opens

803.48 -> geeksforGeeks contains a lot of knowledge

805.624 -> but how to utilize it in the best way

808.6 -> I've tried to tell you about that

809.972 -> how you can practice in the best way

812.7 -> because if you haven't practiced properly then even if you've got a lot of knowledge

816.686 -> that won't come in handy at the correct time

820.214 -> Alright!

820.657 -> So, you've to practice properly.

822.327 -> You've to do a streamlined practice

824.176 -> and things will get better on its own.

827.052 -> Alright!

827.614 -> So, this was the main motive of this video.

829.486 -> Do tell me how the video was.

830.986 -> If you're still struck somewhere, then do tell me, in the comment section.

833.972 -> I'll try to help you.

835.786 -> and with that its time to depart.

836.838 -> We'll meet in the next video.

837.701 -> Do like the video, subscribe to the channel.

839.201 -> I'll meet you all in the next video.

840.158 -> Bye! Bye!

840.818 ->
