Guessing Game

About

This game is a simple guessing game where the user tries to guess a secret number. The computer will give hints to the user if the secret number is higher or lower than the guess.

Requirements

1. Ask the player what the lowest and highest possible secret number should be. Store the limits in variables called lowest and highest.
2. Generate a random number from lowest to highest called secret.
3. Read a guess from the player and tell them if the secret number is higher or lower than the guess.
4. Repeat step 4 until the player guesses the secret number.
5. When the player wins, show the number of guesses they made.

Challenges

1. Stop players from entering invalid input (e.g. text or empty lines).
2. When the player doesn't give a highest or lowest value, use default values.
3. Add a leaderboard to the game. The leaderboard should keep track of the top 10 scores and display them at the end of the game.
