Solution: Reverse Words in a String
Understand how to reverse the words in a string by removing extra spaces, splitting the sentence, and then using the two pointers technique to swap words. Learn to implement a space-efficient and time-optimal solution that preserves the character order within each word and avoids extra spaces in the output.
We'll cover the following...
Statement
You are given a string sentence that may contain leading or trailing spaces, as well as multiple spaces between words. Your task is to reverse the order of the words in the sentence without changing the order of characters within each word. Return the resulting modified sentence as a single string with words separated by a single space, and no leading or trailing spaces.
Note: A word is defined as a continuous sequence of non-space characters. Multiple words separated by single spaces form a valid English sentence. Therefore, ensure there is only a single space between any two words in the returned string, with no leading, trailing, or extra spaces.
