Problem: Counting Bits

Medium
30 min
Explore how to solve the Counting Bits problem by using dynamic programming techniques. Understand how to create an array representing the count of ones in binary forms of numbers up to n. This lesson helps improve your ability to analyze bitwise properties and optimize solutions for coding interview questions.

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
Similar Problems
The Number of Good Subsets
0/1 Knapsack
Coin Change
N-th Tribonacci Number
Partition Equal Subset Sum
01 Matrix
