Longest Word Finder

You are given a string s containing one or more words separated by whitespace. Your task is to find and print the longest word in the string. In the case where multiple words have the same maximum length, output the first occurrence.

Note: The string may contain punctuation, and these punctuation marks are considered part of the words.

For example, given the input "I love programming challenges", the output should be "programming".

The solution should read input from stdin and output the result to stdout.
