Implement the apply function

# Introduction

In this challenge, we will be implementing the `apply` function. The task is to create a function called `myApply` that encapsulates the functionality of the `apply` function. The `myApply` function will take two parameters: the first parameter is the function to be executed, and the second parameter is the context object that needs to be explicitly changed. The `myApply` function should be able to handle cases where the function being executed has arguments.
