Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    if(n == 0 ) return 0;
    else if(n < 0) return 1;
    else
    {
            for(int i = 0; i < n; i++ )
                    {
                        if(1 != (k & (1 << i))) return i;
                    }
    }      
}

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