Swift Algorithm: Check if 2 Strings Contain the Same Characters
Efficiently verify if two strings contain the same characters

This kind of algorithm can be used for password validation, text-based games, detecting duplicate entries in data, and string sanitization.
Create a function that takes two string parameters and returns true if they consist of the same characters, regardless of their order and case sensitivity.
Here’s a sample input and what should be its corresponding output:
- “swift” and “swift” returns true.
- “swift” and “tfiws” returns true.
- “swift” and “iftws” returns true.
- “swift programming” and “programming swift” returns true.
- “swift” and “swift programming” returns false.
- “Swift” and “swift” returns false.
- “swift” and “iftwss” returns false.
Let’s break it down to simplify solving it:
- The first step is to create two parameters to store the first and second strings.
- Since we will be checking each character in a string, let’s transform both the first and second parameters into arrays.
- By sorting both transformed…
