3. Check if K-th Bit is Set

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here

   if( (n>>k)& 1)
        return 1;
    return 0;

}

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

move that one bit to lsb and & with 1 return 1 if that is 1 else 0
