Take a look at the "bitwise" operators for such an operation. Then research the following phrase... (a & b ) << 1, a ^ b. That is a bitwise AND, a left shift operator and an XOR operator. Then research using this in a recursive loop. The whole solution is about 4-6 lines in a function which you can call from main.

If you continue to get stuck, show us what you have done so far and we will see what we can do.
