The Rust Programming Language in a Day: Task #1 - The Lottery

Task description

Write a command line tool that takes a list of numbers for international lotteries, eg. 6 out of 45, 6 out of 49, 5 out of 50, etc.

• cargo run -- 6 45 means to take 6 out of 45
• This will yield 6 random numbers out of a pot of 45 numbers
• Write a struct Lotto representing your Lotto results
• Write a function format_lotto_results that formats your lotto results for pretty printing
• Make sure you adhere ownership and borrowing rules
• Bonus: Allow for multiple runs. E.g. cargo run -- 6 45 6 49 5 50 does three runs: 6 out of 45, 6 out of 49, 5 out of 50
• Use the rand crate for random number generation (this might be helpful)

Working with Codespaces

1. Fork this repo
2. On the upper right corner, there is a button named Code
3. Click the Code button and click "New codespace"
4. A new codespace for you pops up. You can reuse this codespace after creation.

You are all set up with VSCode, Rust, a Terminal, etc.

See more about [Codespaces](GitHub Codespaces)

Tests and execution

1. Run the tests with cargo test. All tests need to pass!

2. Run the app with cargo run -- 6 45. This should be the desired output

6 of 45: [31, 29, 38, 4, 21, 24]

With the numbers being different each time of course!
