Solution: Custom Sort String

Explore how to solve the custom sort string problem by leveraging hash maps to count character frequencies and reorder strings. This lesson helps you understand the application of hash maps in preserving relative character order and optimizing string manipulation with clear steps and complexity analysis.

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.
