Check If a Number Is a Power of Two

Code

#include <stdint.h>
#include <stdio.h>

// Complete the function
const char *is_power_of_two(uint32_t n) {

  if (n != 0 && (n & n - 1) == 0) {
    return "YES";
  } else {
    return "NO";
  }
}

int main() {
  uint32_t n;
  scanf("%u", &n);

  const char *result = is_power_of_two(n);
  printf("%s", result);
  return 0;
}
