Description
You are given a string title
consisting of one or more words separated by a single space, where each word consists of English letters. Capitalize the string by changing the capitalization of each word such that:
- If the length of the word is
1
or2
letters, change all letters to lowercase. - Otherwise, change the first letter to uppercase and the remaining letters to lowercase.
Return the capitalized title
.
Example 1:
Input: title = "capiTalIze tHe titLe" Output: "Capitalize The Title" Explanation: Since all the words have a length of at least 3, the first letter of each word is uppercase, and the remaining letters are lowercase.
Example 2:
Input: title = "First leTTeR of EACH Word" Output: "First Letter of Each Word" Explanation: The word "of" has length 2, so it is all lowercase. The remaining words have a length of at least 3, so the first letter of each remaining word is uppercase, and the remaining letters are lowercase.
Example 3:
Input: title = "i lOve leetcode" Output: "i Love Leetcode" Explanation: The word "i" has length 1, so it is lowercase. The remaining words have a length of at least 3, so the first letter of each remaining word is uppercase, and the remaining letters are lowercase.
Constraints:
1 <= title.length <= 100
title
consists of words separated by a single space without any leading or trailing spaces.- Each word consists of uppercase and lowercase English letters and is non-empty.
