Problem Statement

Separate the string "Hello,How,Are,You,Today" by commas into an array (or list) so that each element of it stores a different word. Display the words to the 'user', in the simplest manner possible, separated by a period. To simplify, you may display a trailing period.

Let's start with the solution:

var s = "Hello,How,Are,You,Today"
var t = s.split(",").join(".") + "."
System.print(t)
