"translatedContent": "<p>字符串压缩。利用字符重复出现的次数,编写一种方法,实现基本的字符串压缩功能。比如,字符串<code>aabcccccaaa</code>会变为<code>a2b1c5a3</code>。若“压缩”后的字符串没有变短,则返回原先的字符串。你可以假设字符串中只包含大小写英文字母(a至z)。</p>\n\n<p> <strong>示例1:</strong></p>\n\n<pre>\n<strong> 输入</strong>:\"aabcccccaaa\"\n<strong> 输出</strong>:\"a2b1c5a3\"\n</pre>\n\n<p> <strong>示例2:</strong></p>\n\n<pre>\n<strong> 输入</strong>:\"abbccd\"\n<strong> 输出</strong>:\"abbccd\"\n<strong> 解释</strong>:\"abbccd\"压缩后为\"a1b2c2d1\",比原字符串长度更长。\n</pre>\n\n<p><strong>提示:</strong></p>\n\n<ol>\n<li>字符串长度在[0, 50000]范围内。</li>\n</ol>\n",
