C Program to check if two given strings are isomorphic to each other

C Program to check if two given strings are isomorphic to each other

A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions.

Given two strings str1 and str2, the task is to check if the two given strings are isomorphic to each other or not.

Two strings are said to be _**_isomorphic_ if there is a _one to one mapping_ possible for every character of _str1_ to every character of _str2_ and all occurrences of every character in _str1 __map to same character in __str2**.

Examples:

Input:_ str1 = “egg”, str2 = “add”_

Output:_ Yes_

Explanation:

‘e’ in str1 with ASCII value 101 is mapped to ‘a’ in str2 with ASCII value 97.

‘g’ in str1 with ASCII value 103 is mapped to ‘d’ in str2 with ASCII value 100.

Input:_ str1 = “eggs”, str2 = “addd”_

Output:_ No_

Hashing Approach: Refer to the previous post for the Hashmap based approach.

Time Complexity:_ O(N)_

Auxiliary Space:_ O(256)_
