/*****************************************************************************************************
*
* Given a string s and an integer array indices of the same length.
*
* The string s will be shuffled such that the character at the i^th position moves to indices[i] in
* the shuffled string.
*
* Return the shuffled string.
*
* Example 1:
*
* Input: s = "codeleet", indices = [4,5,6,7,0,2,1,3]
* Output: "leetcode"
* Explanation: As shown, "codeleet" becomes "leetcode" after shuffling.
*
* Example 2:
*
* Input: s = "abc", indices = [0,1,2]
* Output: "abc"
* Explanation: After shuffling, each character remains in its position.
*
* Example 3:
*
* Input: s = "aiohn", indices = [3,1,4,2,0]
* Output: "nihao"
*
* Example 4:
*
* Input: s = "aaiougrt", indices = [4,0,2,6,7,3,1,5]
* Output: "arigatou"
*
* Example 5:
*
* Input: s = "art", indices = [1,0,2]
* Output: "rat"
*
* Constraints:
*
* s.length == indices.length == n
* 1 <= n <= 100
* s contains only lower-case English letters.
* 0 <= indices[i] < n
* All values of indices are unique (i.e. indices is a permutation of the integers from 0 to n
* - 1).
