Hi everyone.

Is there any collection of problems categorized based on the Data Structure?

For example, people say when you are learning you should be able to solve at least standard problems of specific data structure. I want to know what are those standard problems?

What I can think of is, as parenthesis is a standard problem of stack (or two pointers), binary search is a standard recursion, d&c problem. I am looking for something like this for all the data structures and algos.

Auto comment: topic has been updated by nikhilkarve (previous revision, new revision, compare).Well it really depends on the data structure or the algorithm in question. For example for DP, you have a really good contest on AtCoder. For number theory, Project Euler is a great place. Just look around a little.

But if you still want a one stop place for standard/basic problem of any general data structure or algorithm, I think GeeksForGeeks and Leetcode are good places that you should try out.
