Problem: Counting Bits

Medium
30 min
Explore how to count the number of set bits in binary forms of numbers up to a given limit using dynamic programming. Understand the problem constraints and develop efficient solutions by applying core patterns in coding interviews.

Statement

For a given positive integer, n, your task is to return an array of length n+1n+1 such that for each xx where 0xn0 \leq x \leq n, result[x] is the count of 11s in the binary representation of xx.

Constraints:

  • 0n1040 \leq n \leq 10^4
