This video explains a very important programming interview problem which is to find the number of set bits for all numbers from 0 to N and push them in an array and return as answer.This problem is frequently repeated in interview.There are many approaches to solving this problem but the simplest is to just iterate over all the numbers and every bit of each number and find the count of set bits.This takes O(NlogN) time.I have shown this approach as method-1 in this video.We can further optimize this solution by using simple observations and use extra space of O(N) to just solve it in O(N) time.I have shown the entire intuition with examples and CODE for this optimized solution as method 2.
