Given an IntArray, return true if it contains a 2, 7, 1 pattern: a value, followed by the value plus 5, followed by the value minus 1. Additionally the 271 counts even if the 1 differs by 2 or less from the correct value.

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Kotlin's assert or check methods
