You are given a class, Trimmer, which provides a static method with signature:

public static String trim$($String string$)$

This method accepts a single string parameter and returns $$ trimmed version of it$.$ Trimming removes all the space characters from the beginning and the end of the string.

Examples:

Trimmer. trim$("$Hello world!"$)$

$->$ "Hello world!"

Trimmer.trim$("$ Hello world!

$")->$ "Hello world!

Requirements

Your task is to write a suite of tests to verify the correctness of the trim method.

$2$

$$ Your suite of tests will be run against multiple $($wrong and correct$)$ implementations of the trim method. All tests must pass for correct

$-$implementation. Otherwise, you will receive $0\%$ score. For wrong implementations, at least one test should fail

$$ Tests should be written using Java $11$ and JUnit $4$ framework For assertions, use static methods provided by the org. junit.Assert class, i$.$e$.$ assertEquals, assert$$Not$$Equals$,$etc
