Count Set Bits | Dataford Interview Questions

Cyient embedded firmware often inspects status registers and diagnostic flags represented as unsigned integers. Given a non-negative 32-bit integer n, return the number of set bits, also called 1 bits, in its binary representation.

Use an efficient bit-manipulation approach. The function should count only the bits present in the supplied value and must not convert the integer to a string.

Formal Specification

Implement count_set_bits(n), where:

Input: n, a non-negative integer in the range 0 through 2^32 - 1.
Output: An integer representing the number of set bits in n.

Constraints

0 <= n <= 2^32 - 1
The input is a non-negative integer
Do not convert the integer to a string

Function Signature

def count_set_bits(n):
