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) {
    int count =0;
    for(int i=31;i>=0;i--)
    {
        if(n & (1 << i))
        {
            count++;
        }
    }
    if(count == 1)
    {
        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;
}
