Algorithms

You are given a string <code>s</code> and an integer array <code>indices</code> of the same length. The string <code>s</code> will be shuffled such that the character at the <code>ith</code> position moves to <code>indices[i]</code> in the shuffled string.

Return the shuffled string.

Example 1:
<img alt="" src="https://assets.leetcode.com/uploads/2020/07/09/q1.jpg" style="width: 321px; height: 243px;" />
<pre>
Input: s = &quot;codeleet&quot;, <code>indices</code> = [4,5,6,7,0,2,1,3]
Output: &quot;leetcode&quot;
Explanation: As shown, &quot;codeleet&quot; becomes &quot;leetcode&quot; after shuffling.
</pre>

Example 2:

<pre>
Input: s = &quot;abc&quot;, <code>indices</code> = [0,1,2]
Output: &quot;abc&quot;
Explanation: After shuffling, each character remains in its position.
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>s.length == indices.length == n</code></li>
	<li><code>1 &lt;= n &lt;= 100</code></li>
	<li><code>s</code> consists of only lowercase English letters.</li>
	<li><code>0 &lt;= indices[i] &lt; n</code></li>
	<li>All values of <code>indices</code> are unique.</li>
</ul>

给你一个字符串 <code>s</code> 和一个 长度相同 的整数数组 <code>indices</code> 。

请你重新排列字符串 <code>s</code> ，其中第 <code>i</code> 个字符需要移动到 <code>indices[i]</code> 指示的位置。

返回重新排列后的字符串。

示例 1：

<img alt="" src="https://assets.leetcode-cn.com/aliyun-lc-upload/uploads/2020/07/26/q1.jpg" />

<pre>
输入：s = "codeleet", <code>indices</code> = [4,5,6,7,0,2,1,3]
输出："leetcode"
解释：如图所示，"codeleet" 重新排列后变为 "leetcode" 。
</pre>

示例 2：

<pre>
输入：s = "abc", <code>indices</code> = [0,1,2]
输出："abc"
解释：重新排列后，每个字符都还留在原来的位置上。
</pre>

提示：

<ul>
	<li><code>s.length == indices.length == n</code></li>
	<li><code>1 &lt;= n &lt;= 100</code></li>
	<li><code>s</code> 仅包含小写英文字母</li>
	<li><code>0 &lt;= indices[i] &lt;&nbsp;n</code></li>
	<li><code>indices</code> 的所有的值都是 唯一 的</li>
</ul>
