Share the link of 450 questions , also one thing don’t expect that if u solve this 450 questions u will surely placed in amazon or whatever , practice is the key , I think in the list there are many standard problems on every topic , but it doesn’t mean after solving 30 problems of DP u will be able to solve DP problems of CC /CF / Atcoder .


Yes I am very much aware of what you want to tell me.
Link of the questions is the description of first video.
Please share this with your friends it might help them.


One more , u just solved the question by thinking only passing the test case , don’t do this, as in one question of finding union of two sorted arrays u just did by taking set , no man this is not the approach they want in interview , try with some better approach.


Ohh yes i actually realised this after making the video.
i shall talk about the two pointer approach in the next video.
Thank you.
Please subscribe to the channel and give me more guidance!.
