Isomorphic Strings
Explore how to determine if two strings are isomorphic by creating a fixed one-to-one character mapping. Understand the problem constraints and use hash maps to implement an efficient solution in C++. Develop skills to handle character mapping and ensure consistent replacements while preserving order.
We'll cover the following...
Statement
Given two strings, check whether two strings are isomorphic to each other or not. Two strings are isomorphic if a fixed mapping exists from the characters of one string to the characters of the other string. For example, if there are two instances of the character "a" in the first string, both these instances should be converted to another character (which could also remain the same character if "a" is mapped to itself) in the second string. This converted character should remain the same in both positions of the second string since there is a fixed mapping from the character "a" in the first string to the converted character in the second string. ...
