Reverse a string
For example: input: "cool" output: "looc"
Test your function on this string:
uüu and see what happens. Try to write a function that properly
reverses this string. Hint: grapheme clusters
To get the bonus test to run, remove the ignore flag (
#[ignore]) from the
last test, and execute the tests with:
$ cargo test --features grapheme
You will need to use external libraries (a
crate in rust lingo) for the bonus task. A good place to look for those is crates.io, the official repository of crates.
Check the documentation for instructions on how to use external crates in your projects.
