Algorithms

Write a function to find the longest common prefix string amongst an array of strings.

If there is no common prefix, return an empty string <code>&quot;&quot;</code>.

&nbsp;
Example 1:

<pre>
Input: strs = [&quot;flower&quot;,&quot;flow&quot;,&quot;flight&quot;]
Output: &quot;fl&quot;
</pre>

Example 2:

<pre>
Input: strs = [&quot;dog&quot;,&quot;racecar&quot;,&quot;car&quot;]
Output: &quot;&quot;
Explanation: There is no common prefix among the input strings.
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= strs.length &lt;= 200</code></li>
	<li><code>0 &lt;= strs[i].length &lt;= 200</code></li>
	<li><code>strs[i]</code> consists of only lowercase English letters if it is non-empty.</li>
</ul>

String

编写一个函数来查找字符串数组中的最长公共前缀。

如果不存在公共前缀，返回空字符串&nbsp;<code>""</code>。

&nbsp;

示例 1：

<pre>
输入：strs = ["flower","flow","flight"]
输出："fl"
</pre>

示例 2：

<pre>
输入：strs = ["dog","racecar","car"]
输出：""
解释：输入不存在公共前缀。</pre>

提示：

<ul>
	<li><code>1 &lt;= strs.length &lt;= 200</code></li>
	<li><code>0 &lt;= strs[i].length &lt;= 200</code></li>
	<li><code>strs[i]</code>&nbsp;如果非空，则仅由小写英文字母组成</li>
</ul>
