Easy • View on LeetCode • View on GitHub

Problem Description

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.

Solution

/**
 * @param {string} s
 * @param {number[]} indices
 * @return {string}
 */
var restoreString = function(s, indices) {
  return indices.reduce((result, index, offset) => {
    result[index] = s[offset];
    return result;
  }, new Array(indices.length)).join('');
};
