3. Check if K-th Bit is Set

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    int mask, is_set;
    mask = (1 << k);

    is_set =(n & mask);
    if(is_set !=0)
    {   
        return 1;

    }
    else
    {
        return 0;

    }

}

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