Reverse Words in a String

Given a string consisting of words separated by spaces, your task is to reverse the order of the words. The input string may contain leading or trailing whitespaces and may contain multiple spaces between words. You should remove any extra spaces and print the reversed words in a single line separated by a single space.

Note: A word is defined as a sequence of non-space characters.

For example, if the input is Hello world this is a test , the output should be test a is this world Hello.
