Comprobar si un número tiene el mismo número de bits activados y desactivados

Dado un número N, la tarea es comprobar si el recuento de bits activados y desactivados en el número dado es el mismo. 
Ejemplos: 
 

Input: 12
Output: Yes
1100 is the binary representation of 12
which has 2 set and 2 unset bits 

Input: 14
Output: No

Enfoque: Recorra la representación binaria del número dado, verifique si el bit más a la izquierda está configurado o no usando n & 1 . Si n & 1 devuelve 1, entonces se establece el bit más a la izquierda. Correcto, cambie el número cada vez por 1 para verificar el siguiente bit. Una vez que la representación binaria se recorre por completo, compruebe si el número de bits activados y desactivados es el mismo. Si son iguales, escriba «SÍ», de lo contrario, escriba «NO». 
A continuación se muestra la implementación del enfoque anterior:

// has same number of set and unset bits
#include <bits/stdc++.h>

// Function to check if a number

    // iterate for all bits of a number
    while (n) {
 
        // if set
        if (n & 1)
            set++;
        // if unset
        else
            unset++;
 
        // right shift number by 1
        n = n >> 1;
