Algorithms

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. Capitalize the string by changing the capitalization of each word such that:

<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>

Return the capitalized <code>title</code>.

&nbsp;
Example 1:

<pre>
Input: title = &quot;capiTalIze tHe titLe&quot;
Output: &quot;Capitalize The Title&quot;
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.
</pre>

Example 2:

<pre>
Input: title = &quot;First leTTeR of EACH Word&quot;
Output: &quot;First Letter of Each Word&quot;
Explanation:
The word &quot;of&quot; 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>

Example 3:

<pre>
Input: title = &quot;i lOve leetcode&quot;
Output: &quot;i Love Leetcode&quot;
Explanation:
The word &quot;i&quot; 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>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= title.length &lt;= 100</code></li>
	<li><code>title</code> consists of words separated by a single space without any leading or trailing spaces.</li>
	<li>Each word consists of uppercase and lowercase English letters and is non-empty.</li>
</ul>

String

给你一个字符串&nbsp;<code>title</code>&nbsp;，它由单个空格连接一个或多个单词组成，每个单词都只包含英文字母。请你按以下规则将每个单词的首字母 大写&nbsp;：

<ul>
	<li>如果单词的长度为&nbsp;<code>1</code>&nbsp;或者&nbsp;<code>2</code>&nbsp;，所有字母变成小写。</li>
	<li>否则，将单词首字母大写，剩余字母变成小写。</li>
</ul>

请你返回 大写后&nbsp;的&nbsp;<code>title</code>&nbsp;。

&nbsp;

示例 1：

<pre>输入：title = "capiTalIze tHe titLe"
输出："Capitalize The Title"
解释：
由于所有单词的长度都至少为 3 ，将每个单词首字母大写，剩余字母变为小写。
</pre>

示例 2：

<pre>输入：title = "First leTTeR of EACH Word"
输出："First Letter of Each Word"
解释：
单词 "of" 长度为 2 ，所以它保持完全小写。
其他单词长度都至少为 3 ，所以其他单词首字母大写，剩余字母小写。
</pre>

示例 3：

<pre>输入：title = "i lOve leetcode"
输出："i Love Leetcode"
解释：
单词 "i" 长度为 1 ，所以它保留小写。
其他单词长度都至少为 3 ，所以其他单词首字母大写，剩余字母小写。
</pre>

&nbsp;

提示：

<ul>
	<li><code>1 &lt;= title.length &lt;= 100</code></li>
	<li><code>title</code>&nbsp;由单个空格隔开的单词组成，且不含有任何前导或后缀空格。</li>
	<li>每个单词由大写和小写英文字母组成，且都是 非空&nbsp;的。</li>
</ul>
