In this assignment, we'll be continuing to build programs with if statements. As usual, start off by forking then cloning this repository.

You've been contracted to write the software for a lock box.

Write a program called lock-box.js that stores the pin code to the lock box in a variable at the top of your program (i.e.: const pinCode = '1234';).

After that, use prompt-sync to prompt the user for the passcode. If the user gets the passcode exactly correct, log a success message containing the word, "success". If not, log a failure message containing the word, "failure".

Note: In this assignment, the node_modules folder containing the prompt-sync dependency does not already exist. To add it to this project, navigate to this repository using the command line then install it using the Node Package Manager with npm install prompt-sync.

You've once again been contracted to write a program, this time for an app that helps two people split a bill at a restaurant evenly.

Write a program called bill-splitter.js that prompts the user for how much Person 1 paid, then for how much Person 2 paid. It should then log out the message, 'Person 1 owes $' or 'Person 2 owes $' depending on who owes who.

Write a new program that expands on bill-splitter.js this program should be able to split a bill between three people! Once again, prompt the user for how much each person paid. Then, log out messages indicating who needs to pay who.

You'll probably need to use a system of equations to solve this!
