Problem: Custom Sort String

Medium
30 min
Explore how to implement a custom sort for strings by using hash maps to maintain character order. This lesson helps you understand how to rearrange one string to match the relative order of characters from another, focusing on problem constraints and practical solution techniques.

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.
