Solution: Custom Sort String
Understand how to solve the Custom Sort String problem by applying hash maps to count character frequencies of a given string and reorder it based on a custom character sequence. Learn how to build a result string that respects the specified order, handle characters not in the order, and analyze the solution's time and space complexity for effective coding interview preparation.
We'll cover the following...
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.
