mandatory

Write a function that returns the number of bits you would need to flip to get from one number to another.

  • Prototype: unsigned int flip_bits(unsigned long int n, unsigned long int m);
  • You are not allowed to use the % or / operators

/**
 * main - check the code

 * Return: Always 0.
 */
int main(void)
{
    unsigned int n;

    n = flip_bits(1024, 1);
    printf("%u\n", n);
    n = flip_bits(402, 98);
    printf("%u\n", n);
    n = flip_bits(1024, 3);
    printf("%u\n", n);
    n = flip_bits(1024, 1025);
    printf("%u\n", n);
    return (0);
