Problem: Custom Sort String

Medium
30 min
Explore how to reorder a given string so its characters appear in the relative order defined by another string. Understand the logic behind using hash maps to achieve this custom sorting under given constraints. This lesson helps you implement solutions that maintain character order efficiently.

Statement

Given two strings, order and s, where all characters in order are unique and arranged in a custom order, return any permutation of s that satisfies the following condition:

The characters in the permuted s should appear in the same relative order as they do in order. Specifically, if a character x appears before a character y in order, then x must also appear before y in the permuted string.

Constraints:

  • 11 \leq order.length 26\leq 26

  • 11 \leq s.length 200\leq 200

  • order and s consist of lowercase English letters.

  • All the characters of order are unique.
