【Leetcode】1528. Shuffle String
題目地址：
https://leetcode.com/problems/shuffle-string/
給定一個字串 s s s和一個陣列 a a a，要求返回一個新字串 t t t使得 t [ a [ i ] ] = s [ i ] t[a[i]]=s[i] t[a[i]]=s[i]。
程式碼如下：
public class Solution {
public String restoreString(String s, int[] indices) {
char[] str= new char[s.length()];
for (int i = 0; i < s.length(); i++) {
str[indices[i]] = s.charAt(i);
}
return new String(str);
}
}
時空複雜度 O ( l s ) O(l_s) O(ls)。
