Solution: Custom Sort String

Understand how to solve the custom sort string problem by using hash maps to count character frequencies and reorder a given string according to a specified character order. This lesson teaches efficient string manipulation and hashing techniques essential for coding interviews.

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 ...
