Problem: Counting Bits

Easy
15 min
Explore how to count the number of 1s in the binary representation of integers using dynamic programming. This lesson helps you understand the problem statement and develop an efficient solution approach through hands-on coding practice.

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 0≤x≤n0 \leq x \leq n, result[x] is the count of 11s in the binary representation of xx.

Constraints:

  • 0≤n≤1040 \leq n \leq 10^4
