Reverse a number using recursion

Recursion is a programming technique where a function calls itself repeatedly until a specific condition is met. It is a powerful and elegant tool that can be used to solve complex problems, including reversing a number. In this article, we will explore how to reverse a number using recursion.

To reverse a number using recursion, we first need to understand how to reverse a number using a loop. Let's consider the number 1234. To reverse this number, we would do the following:

  1. Extract the last digit (4) and add it to a new variable.
  2. Remove the last digit (4) from the original number (123).
  3. Repeat steps 1 and 2 until all digits have been extracted.
  4. The reversed number is the new variable (4321).
