Check if K-th Bit is Set

Code

#include <stdio.h>
#include <math.h>
int isKthBitSet(int n, int k) {
    // Write your code here
    n &= (int)pow(2,k);
    if(n == (int)pow(2,k))
    return 1;
    else 
    return 0;
}

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