3. Check if K-th Bit is Set

#include <stdio.h>

#define TRUE 1
#define SET  1
#define FALSE 0
int isKthBitSet(int n, int k) {
    int mask = (1 << k); // 
    n &= mask;
    if(n >> k == SET)
    {   
        return TRUE;
    }

    return FALSE;
    
}

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