There are two kinds of exercise. One is a binary and the other is a library.
The binary exercises can be run with cargo
cargo run --bin hello-worldBoth kinds of exercises come with tests. You can run the tests for a specific exercise using cargo.
cargo test -p hello-worldSome exercises have more than one test. Giving the prefix of a test you want to run will scope down the tests to the ones that match that prefix.
cargo test -p hello-world outputsample output
