Shuffle String

Problem statement​

You are 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 ith 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.

Constraints:

  • s.length == indices.length == n
  • 1 <= n <= 100
  • s consists of only lowercase English letters.
  • 0 <= indices[i] < n
  • All values of indices are unique.

My solution​

/**
 * @param {string} s
 * @param {number[]} indices
 * @return {string}
 */
var restoreString = function(s, indices) {
  const arr = Array.from(new Array(s.length));
    
    indices.forEach((idx, i) => {
        arr[idx] = s.charAt(i)
    })
    
    return arr.join("")
};
