Reverse Bits

Understand how to reverse the order of bits in a 32-bit unsigned integer using bitwise manipulation. This lesson helps you develop an optimal solution with constant time and space complexity while addressing challenges such as signed integer representation in some languages. Practice this fundamental pattern to enhance your problem-solving skills 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 ...
