Bit Manipulation pattern
Reverse Bits
Reverse the bits of an unsigned integer (the real problem is 32-bit; we use 8 bits here for clarity). 00101011 (43) becomes 11010100 (212). Watch it run step by step, then write your own pseudocode and get it checked by AI.

The approach
- 01 Build result bit by bit O(WIDTH) = O(32)O(1) space
What you will learn
- How to read Reverse Bits and spot the bit manipulation pattern in it
- Build result bit by bit: O(WIDTH) = O(32) time, O(1) space
- The pseudocode for each approach, its line lit as the animation runs
