Content
0 -> So when we do coding
1.997 -> Or when we study DSA
3.382 -> Then what's the main problem which we face
4.642 -> That we cannot stay consistent
6.365 -> And because of not being consistent
8.397 -> We are unable to achieve our aims
11.041 -> We think that we will complete DSA in 3-4 months
14.325 -> But we do it for 1,2,3 days
16.874 -> After that someone's marriage comes
19.121 -> Some's function comes
20.196 -> Friend's birthday comes
21.086 -> And then our flow breaks
23.649 -> Then we become lazy for one more day
25.871 -> And then back to square one
26.864 -> So for this I have a nice solution
29.05 -> That we gonna discuss in today's video
30.995 -> So your best free resource
34.052 -> to learn data structures
35.616 -> We are going to talk about that in today's video
37.378 -> Other than this we face one more problem
39.027 -> That we did the question 2 months before
41.606 -> And then we revisit that question after sometime, we forget that
45.715 -> It seems like that I did it
47.546 -> It seems familiar
49.142 -> But it is not coming in mind
50.119 -> We generally do not know that which questions we have to do
51.727 -> Do we have to do company wise questions
53.402 -> We do not have to do company wise
54.514 -> Do we have to do topic wise or not
56.897 -> So we gonna talk about all these things in today's video
59.594 -> So lets start the video without any delay
61.631 -> Before starting the video, do like the video
64.014 -> Subscribe the channel if you haven't done yet
66.748 -> And now lets start the video without any delay
69.342 -> Now you must have seen a video, 90 days DSA roadmap
73.746 -> In that I told that how can you complete your DSA in 90 days
77.408 -> Now lets go through that once
79.433 -> So that you can be helped with your consistency
82.103 -> After that we come to our main topic
83.357 -> That I am going to tell you. Best free resources to learn data structures and algorithms
87.048 -> Now I know that most of the people have seen this roadmap
91.624 -> I divided all the topics in this
93.993 -> Let me just give you an overview
96.73 -> Other than that, How to use it , you can check out the video. It will be coming in i button
100.996 -> But let me tell you once
103.435 -> That how and what things you have to do
104.89 -> So that you get a little bit idea
106.251 -> And then you start your work
108.674 -> In first 1-2 days, you can learn basic time complexity and all
112.013 -> After that in 3-4 days, you can easily do recursion, backtracking
115.006 -> After that by completing, arrays, linked list, stacks, queues, you can start giving contests and all
120.06 -> This is also a very important suggestion, important point that we gonna discuss with that platform or that resource
126.173 -> After that you can see searching, sorting, hashing, heaps, sliding window, graphs, DP
132.314 -> This all is divided
133.058 -> So that it is easier for you that what thing you have to start
135.688 -> After that which thing you have to do
136.472 -> And by following this
138.744 -> You can study data structures and algorithms very nicely
141.44 -> Now lets come to Geeks for geeks
143.233 -> Now everyone has listen the name of geeks for geeks
145.37 -> When we come in college in first year
147.979 -> So we ask that from where we have to study, how to study
149.84 -> So any senior or any other person will say that study from geeks fro geeks
153.747 -> And when we get any doubt related to computer science
156.127 -> And we do not understand, from where we have to see, what to see
158.831 -> So I personally do this
160.133 -> I write that question and GFG, and any article comes. And all the things get solved after reading that article
165.941 -> Now if you want to study any topic that I have given there on 90 days roadmap
169.628 -> So what can you do
170.318 -> You can go to data structures here
171.501 -> And then you can read that particular topic from here
175.076 -> And when you have to practice for that particular topic,
177.62 -> What will you write?
178.341 -> Practice Geeks for geeks
180.285 -> And you will get practice.geeksforgeeks.org here
184.48 -> Here each and every question is aggregated
187.63 -> Many more things are also here
189.142 -> We gonna discuss about all of that one by one
190.925 -> So assume you have read linked list
193.128 -> In our 90 days challenge, we came to our day 11-30 and after completing arrays, we are doing linked list
199.83 -> So what we will do
200.527 -> We will go to the linked list data structure
202.044 -> Here you will get the complete list
204.412 -> Each and every question that is asked
207.667 -> And what is its level. Is it easy , medium or hard
210.252 -> So you can do all those things here
212.905 -> So what you have to do, you have to maintain a ratio
214.843 -> 2, 5 or 3
216.084 -> now what is the meaning of 2,5 ,3
217.133 -> You have to do 2 easy questions, 5 medium questions
221.089 -> Because medium questions are asked more
222.906 -> And after that you have to try 3 hard questions
225.081 -> Of that topic. Means you have to do this for every topic
228.068 -> This is the ratio
228.71 -> Lets say you have to do 100 questions of a topic
230.555 -> Then you will be doing 30,50 ,20
233.387 -> If you have to do 20 questions,
234.493 -> You will be doing those questions in the same way
236.793 -> So you have to keep this in mind
238.096 -> Other than this if you have to prepare particularly for any company
242.231 -> Lets say it is amazon
243.449 -> If you have to practice for amazon
245.07 -> So what can you do
246.887 -> You applied that amazon filter
247.942 -> And whichever questions are asked in amazon
249.968 -> Till now
250.5 -> You will get question bank type of that
252.324 -> You can practice these questions
254.152 -> So that your practice can be done up to a bar level
257.459 -> and things get cleared to you
260.018 -> Now next thing that comes, that I was saying you from the starting
262.481 -> Consistency cannot be maintained
264.272 -> 90 days got completed . You studied DSA nicely
266.783 -> What after that?
267.637 -> It is mandatory to maintain consistency until you do not get a job
272.122 -> Otherwise you start forgetting concepts
274.202 -> So we discussed the second point
275.667 -> That we start forgetting things
276.996 -> So here is one thing named POTD
279.262 -> Problem of the day
280.989 -> Now GFG has launched this very recently
283.669 -> Now here you will be getting a problem daily
286.02 -> If you will solve that problem, You will get getting some geek bits
288.484 -> You can redeem those geek bits
291.074 -> in amazon vouchers, courses, T-shirts, goodees, many things
295.035 -> So as you will see here
296.52 -> this is the nomenclature
297.6 -> Solve a problem to get a geek bit
299.363 -> If you successfully solve problems for 8 consecutive days
302.33 -> You will get 8 additional geek bits
304.586 -> And you must have 50 to get prizes and all
307.774 -> So here you can see what things you can get
310.274 -> Like this is for today. Find length of a loop
314.59 -> We will go to the solve problem
316.494 -> And here you can see , you have to solve the problem
320.08 -> Now the UI of GFG's practice portal plus the test cases has improved a lot
327.046 -> I remember when I used to practice during my internship
329.785 -> Many times , n^3 solution also used to get passed
333.223 -> It doesn't happen now
333.656 -> So this is a very good improvement, this is a very nice thing
336.753 -> And now what happens here
337.993 -> Any problem will come. Like this POTD problem
341.037 -> You will get the question here. They will make you understand the question
342.562 -> You will get the examples and all
343.869 -> You have to code here and submit it
345.701 -> You will compile it
346.818 -> Other than that there is an editorial
348.883 -> If you go in editorial, then you will not get your geek bit
353.082 -> If you are unable to solve the question, you can go to editorial
355.801 -> And you can read in editorial
357.284 -> That how I have to solve this question
359.258 -> As you can see here
360.272 -> You will get all the approaches
361.979 -> A to z
362.501 -> Abd in multiple languages C++, Java, Python, Javascript
366.736 -> you get approaches and all in all
368.101 -> And you get time complexity and all here
370.906 -> So you can practice nicely from here
373.941 -> Other than this, your submissions comes here
375.598 -> That before this, when you solved this question
378.432 -> How much time did you take
379.901 -> And if your all the test cases were passed or not
382.806 -> And what code did you used
383.861 -> If you forget that what did you code
386.571 -> This is a good way that put comments on this problem altogether
389.84 -> I used to make github repository
391.803 -> By putting comments altogether
393.092 -> And uploaded that code on github
394.593 -> So that If I will have to revisit later
396.695 -> That how did I solved this thing
397.796 -> That time it came in mind
399.222 -> But now I am unable to understand what we have to do
400.651 -> So saw it
402.361 -> Now Geeks for geeks has started organizing so many events too
404.654 -> Like many series
406.771 -> Like interview series, job-a-thon, Problem of the day. Let me tell you about these
410.156 -> Other than this, many contests happens
412.05 -> Hiring contests as well as hiring challenges happens
414.591 -> Job-a- thon is for job
417.008 -> will tell you later
419.019 -> Many webinars happens and workshops keeps happening
421.365 -> So you can participate in these
423.155 -> Most of these are free
424.66 -> Free of cost. You do not have to give money
426.533 -> Now let me tell you first what are series
428.137 -> Now what happens in interview series
429.939 -> There is a test of 3 questions in 90 minutes
431.679 -> This happens every Sunday 7 PM IST
434.269 -> Abd its solutions remains on YouTube
436.941 -> GFG has a YouTube channel on which they discuss the solutions later
439.709 -> So if you were unable to solve any question, You can see there
442.901 -> Those people will make you understand nicely
444.257 -> And what is the benefit of giving this contest
446.359 -> I always say that giving contests is very important
449.775 -> Now lets say there is a cricketer
452.331 -> He net practiced a lot
455.025 -> But he hasn't played in the main match
456.985 -> Now after net practicing, you will not have that much idea
459.846 -> That actually when there is pressure in match, there exists so many people, so much crowd
464.018 -> Many things happens
465.097 -> Time , balls
466.514 -> And if you will be able to perform in that or not
468.362 -> Similarly when you sit in a contest
471.692 -> Or you sit in a real interview
473.17 -> You feel that pressure
475.693 -> Time is going to be up
477.676 -> You are seeing the list that these people have done these questions
480.969 -> So that real world scenario that is created
484.838 -> That is created by contest
485.845 -> So this is very important
487.184 -> When you reach to a decent level, then giving contest becomes very important for you
491.502 -> So you can definitely check out this series thing
494.24 -> Next is your job-a-thon
496.211 -> Now what happens in job-a-thon
497.415 -> It is also a proper contest type
499.697 -> And many companies conduct a contest in collaboration
503.694 -> On GFG
504.164 -> And those who are top performers in that
506.227 -> They give interview calls to them
508.135 -> And then you can crack job and all
510.494 -> This is also very good
511.659 -> You can see, there are 18 questions and 175 marks
513.265 -> and 150 minutes
514.712 -> So monthly hiring challenge happens every month
517.341 -> So you can participate in this
519.013 -> Means your practice will happen by participating
521.339 -> And if you get the offer, then it is well and good
522.983 -> Other than this they have started 1-2 more things
525.469 -> Like Bi-wizard school contest
526.824 -> For school kids
527.864 -> If any school kid is watching
529.706 -> You can definitely check this out
531.498 -> And aim GATE. Like GATE exam happens for that
534.182 -> Test series and all are there
535.551 -> So for that also they have started
536.821 -> You can participate in them also
538.656 -> If you are preparing for GATE
540.26 -> Other than this, Geeks for geeks also have many paid courses as well
543.178 -> If you think that free things don't work for you
546.169 -> If you feel that you are not able to read articles on Geeks for geeks
547.862 -> Or you feel that free videos are not enough for you
550.293 -> So you can try this also
552.547 -> Means they are very good
554.026 -> So in that, you can use code NISHANT
557.188 -> And you will get 10% off
559.327 -> And last thing left, you did practice and everything
562.214 -> And finally you need a job
564.372 -> So for job , they have created their job portal
567.098 -> It is here by the name get hired
568.2 -> You can see it
569.167 -> You just have to apply for the job
572.426 -> You will get interview calls and all
573.736 -> You just have to give interview then you will get the job
575.348 -> So this is the whole scenario, this is the whole thing
578.075 -> And thank you so much for watching the video
579.369 -> You will get all the links in the description
582.041 -> You can check out
583.392 -> And start practicing
585.538 -> And if you haven't watched the 90 days roadmap video
589.412 -> So must see that
590.655 -> Thank you so much for watching the video
