Reverse Words

You are given a string S. Your task is to output a new string in which the order of words is reversed.

A word is defined as a non-empty sequence of characters separated by whitespace. If the input string contains only spaces or is empty, output an empty string.

Note: In this problem, multiple consecutive whitespace characters should be treated as a single delimiter.

For example, if S = "hello world from coding assessment", then the output should be "assessment coding from world hello".

inputFormat

The input is provided via standard input (stdin) and consists of a single line containing the string S which may include multiple words separated by spaces.

outputFormat

The output should be printed to standard output (stdout) and consists of a single line containing the words of S in reversed order separated by a single space.

hello

hello
