Solution: Custom Sort String
Explore how to implement a custom sort string solution by using hash maps to count character frequencies in a string. Learn to reorder characters based on a given order string while maintaining relative positions, optimize for time and space complexity, and understand the approach through step-by-step logic.

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.
