Problem: Reverse Bits

Medium
30 min
Understand how to reverse the bits of a 32-bit unsigned integer by changing their order from left to right. Explore bitwise manipulation techniques and implement an efficient solution with constant time and space complexity. This lesson helps you develop skills to solve similar bitwise problems in coding interviews.

Statement

Given an unsigned 32-bit integer n, we need to calculate a 32-bit unsigned integer with reversed bits. When we say “reverse” we don’t mean flipping the 00s to 11s and vice versa, but simply reversing the order in which they appear, i.e., from left-to-right to right-to-left.

Constraints:

  • The input must be a binary string of length 3232
