1528. Shuffle String

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.

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).

class Solution {
    public String restoreString(String s, int[] indices) {
        int n = s.length();
        char[] arr = new char[n];
        for(int i = 0; i < n; i++){
            arr[indices[i]] = s.charAt(i);
        }
        return new String(arr);
    }
}
