    2129 - Capitalize the Title.

    Easy

    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 or 2 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.
