Reverse Bits
#15bit-manipulationdivide-and-conquer
Reverse the bits of a 32-bit unsigned integer.
Example:
Input:
00000010100101000001111010011100Output:
00111001011110000010100101000000Common Mistakes:
- Not processing all 32 bits
- Confusing with reversing integer value
- Not using unsigned right shift (>>> in some contexts)
Notes:
Process bit by bit: extract rightmost bit from input, add to leftmost position of result. Use >>> for unsigned shift if needed. Time: O(1) - always 32 bits.
