Check If a Number Is a Power of Two

Code

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

// Complete the function
const char* is_power_of_two(uint32_t n) {
    // Your logic here
    if(n == 0){
        return "NO";
    }
    if(n == 1){
        return "YES";
    }
    uint32_t shifted_right = (n >> 1);
    uint32_t shifted_left = (n << 1);
    if(shifted_right*4 == shifted_left){
        return "YES";
    }
    return "NO";
}

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

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