3. Check if K-th Bit is Set

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
if((k >= 0) && (k <= 8) ){
    int mask = (1 << k);
    if(mask & n){
return 1;
    }
    else{
        return 0;
    }
}

}

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