Reverse Dot Separated Words

Given a string in which words are separated by dots, your task is to reverse the order of the words. For example, if the input is i.like.this.program.very.much, then the output should be much.very.program.this.like.i.

The string may consist of a single word without any dots, in which case the output remains unchanged. This problem tests your ability to manipulate strings and arrays effectively.

inputFormat

The input consists of a single line containing a string where words are separated by a dot character ('.').

outputFormat
