Do you mean swap two 10-digit numbers, or reverse one 10-digit number (swap end for end)?

An easy way to reverse a number: read the number as a string and reverse the string by looping from the end to the beginning as you print it. If you use this method, then negative numbers require special handling.

There are a few ways to swap two numbers. The simplest way involves using a third variable as a temporary holding place.
