Check If a Number Is a Power of Two

Code

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

// Complete the function
const char* des[]={"NO", "YES"};
const char* is_power_of_two(uint32_t n) {
    if(n==0) return "NO";
    return des[(n&(n-1))==0];
}

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

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