Normalize Sentence Spacing
Easy
You are given a string s, which may contain words, extra spaces between words, and leading or trailing spaces.
Your task is to reformat the string to a "normalized" version. A normalized string has all its words separated by exactly one space, with no spaces at the beginning or end of the string.
Input Format:
The first line of input contains a single string s.
Output Format:
Print the reformatted string on a single line.
Note:
A "word" is defined as any sequence of non-space characters.
If the input string is empty or contains only spaces, the output should be an empty string.
