3. Check if K-th Bit is Set

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    //int bitmask = (1 << k);
    //int isValid = n & bitmask;

    if ((n & ((1 << k))) > 0){
        return 1;
    }
    else{
        return 0;
    }
}

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