/**

* ReverseNumber return the reversed value of the given number.

* @param {Number} n any digit number.

* @returns `Number` n reverse in reverse.

const ReverseNumber = (number) => {

// firstly, check that input is a number or not.

// A variable for storing the reversed number.

let reverseNumber = 0

// Iterate the process until getting the number is 0.

// add to the last digit to in reverseNumber

// reduce the actual number.
