Count Set Bits Efficiently | Dataford Interview Questions

Implement a bitwise operation to count the number of set bits in an integer.

Implement count_set_bits(n), which receives a non-negative 32-bit integer and returns the number of 1 bits in its binary representation. Use bitwise operations rather than converting the integer to a string.

Constraints

0 <= n <= 2^32 - 1
Return an integer count
Use bitwise operations and do not convert n to a string

Function Signature

def count_set_bits(n):
