30. Count Set Bits in an Integer

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
int count = 0;
    while(n>1)
    {
        if(n%2 == 1)
        {
            count++;
        }
        
        n = n/2;
    }
    if(n==1)
    {
        count++;
    }
    return count;
}

int main() {
    int n;
    scanf("%d", &n);
    printf("%d", countSetBits(n));
    return 0;
}
