  • 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);
        }
    }
