Reverse a number

easyMaths and loops10 XP

Return the digits of n (0 or more) in reverse order, as a number: 120 becomes 21. Try it with % and // (JavaScript: Math.floor) instead of strings.

Examples

Input: n = 1234
Output: 4321
Input: n = 120
Output: 21

Examples use JSON: true/false/null are True/False/None in Python.
