Take any 2 numbers and converts into binary format and find the number of bits flipped in between 1st and 2nd number?

Question

For example
2 numbers are 7, 10
Binary digits of 7 is :  00000111
Binary digits of 10 is :00001010
Output is :3. Because Here 3 digits are  flipped.

Answer 1

int temp = 0;

int count = 0;

while both numbers are not 0, temp = first & second. If temp == 0 the count++ (if not then don't increase count). Then right shift both numbers by 1 bit and continue until both are 0. Output the count.
