Problem: Isomorphic Strings

Explore how to determine whether two strings are isomorphic by applying hash tables. Learn to implement a bijective mapping between characters of two strings, ensuring consistent and unique mappings. Understand how to verify this mapping efficiently using dual hash maps and analyze the solution's time and space complexity.

Statement

Given two strings s and t, determine whether they are isomorphic.

Two strings are considered isomorphic if there exists a one-to-one mapping from every character in s to a character in t such that replacing each character in s according to this mapping produces t. The mapping must preserve character order. Every occurrence of a given character in s must map to the same character in t, and no two distinct characters in s may map to the same character in t. A character is allowed to map to itself.

Return TRUE if s and t are isomorphic, and FALSE otherwise.

Note: The mapping must be bijective, meaning it is both one-to-one (no two characters in s map to the same character in t) and consistent (each character in s always maps to the same character in t).
