Problem: Reverse Bits

Medium
30 min
Explore how to reverse the bits in a 32-bit unsigned integer by understanding bitwise manipulation techniques. This lesson helps you implement an optimal O(1) time and space solution to invert bit order without flipping the actual bit values.

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
Similar Problems
Complement of Base 10 Integer
Flipping an Image

Single Number II
Encode and Decode Strings
Find the Longest Substring Having Vowels in Even Counts
Longest Subarray With Maximum Bitwise AND
Count Triplets That Can Form Two Arrays of Equal XOR
Sum of All Subset XOR Totals
Find The K-th Lucky Number
