30. Count Set Bits in an Integer

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
    int count =0;
    for (int i =0; i<32 ; i++)
    { 
        count =(((n>>i)&1) ==1) ? (count +1) : (count);
    }
    return count;
}

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