Problem: Custom Sort String

Medium
30 min
Understand how to implement a custom sort for strings by leveraging hash maps. This lesson helps you reorder characters in one string according to the relative order defined in another string using efficient strategies. You will practice identifying conditions and developing a solution that respects the specified custom sorting rules.

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.
