<p>You are given a string <code>title</code> consisting of one or more words separated by a single space, where each word consists of English letters. <strong>Capitalize</strong> the string by changing the capitalization of each word such that:</p>
|
|
|
|
<ul>
|
|
<li>If the length of the word is <code>1</code> or <code>2</code> letters, change all letters to lowercase.</li>
|
|
<li>Otherwise, change the first letter to uppercase and the remaining letters to lowercase.</li>
|
|
</ul>
|
|
|
|
<p>Return <em>the <strong>capitalized</strong> </em><code>title</code>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> title = "capiTalIze tHe titLe"
|
|
<strong>Output:</strong> "Capitalize The Title"
|
|
<strong>Explanation:</strong>
|
|
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.
|
|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> title = "First leTTeR of EACH Word"
|
|
<strong>Output:</strong> "First Letter of Each Word"
|
|
<strong>Explanation:</strong>
|
|
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.
|
|
</pre>
|
|
|
|
<p><strong>Example 3:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> title = "i lOve leetcode"
|
|
<strong>Output:</strong> "i Love Leetcode"
|
|
<strong>Explanation:</strong>
|
|
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.
|
|
</pre>
|
|
|
|

|
|
<p><strong>Constraints:</strong></p>
