Shuffle String

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.

SOLUTION:

class Solution:
    def restoreString(self, s: str, indices: List[int]) -> str:
        n = len(s)
        op = " " * n
        for i in range(n):
            op = op[: indices[i]] + s[i] + op[indices[i] + 1 :]
        return op
