Reverse a Number
excerpt: This covers the basic building blocks such as Modulo Operator, Reducing in Input by Integer Division and Place Value tags: modulooperator reducinginputvalue placevalue
Write a function to reverse a given number.
 Extract the last number by using Modulo operator.
 Take the digit’s position in the result into account (10, 100, 1000 etc). This is the Place Value in action.
 Add it to reversed digit with extracted digit from the input number.
