3. Check if K-th Bit is Set

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    unsigned char mask = 1;
    unsigned char data = n;
    unsigned char result;
    mask = mask << k;
    result = ((mask & data)!=0);
    return result;

}

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