5 - Reverse Words in a String

Problem Statement​

Given a sentence, reverse the order of its words without affecting the order of letters within a given word.

Example 1:

Input: sentence = "We love Python"
Output: "Python love We"

Example 2:

Input: sentence = "Hey"
Output: "Hey"

Constraints:​

  • The length of the sentence should be equal to or more than one character or word.
  • Sentence contains English uppercase and lowercase letters, digits, and spaces.
  • 1 ≤ sentence.length ≤ 104
  • The order of the letters within a word is not to be reversed.

Note: The input string may contain leading or trailing spaces or multiple spaces between words. The returned string, however, should only have a single space separating each word. Do not include any extra spaces.
