I often go through this dilemma during practicing.

Implementing problems and getting them accepted gives me a feeling of "actually solving" the problem.

However, the number of concepts and ideas I'm getting exposed to is much lesser this way as I am spending a lot of time implementing solutions.

What do you suggest? Which method has helped you improve?

Given an array A of n elements and queries of type (l r k),find the number of occurrences of k in the range l to r

If there are no updates, we can solve the problem by having a map<int,vector> and doing a binary search.

But what if there are updates involved.

I read somewhere that we can use bit..

But I am not sure how that would be useful

Thank you in advance
