Lambda Expressions For Data Operations

# Introduction

In this challenge, we will be using Lambda expressions to perform data operations. The goal is to sort a set of numbers in descending order using `Arrays.sort()`, and convert a set of strings to a collection and iterate through them using `forEach()` method. The challenge requires the use of the `(parameters) -> expression` or `(parameters) -> { statements; }` format of Lambda expressions to complete the tasks.
