Reverse String
Welcome to Reverse String on Exercism's Rust Track.
If you need help running the tests or submitting your code, check out HELP.md.
Introduction
Reversing strings (reading them from right to left, rather than from left to right) is a surprisingly common task in programming.
For example, in bioinformatics, reversing the sequence of DNA or RNA strings is often important for various analyses, such as finding complementary strands or identifying palindromic sequences that have biological significance.
Instructions
Your task is to reverse a given string.
Some examples:
- Turn
"stressed"into"desserts". - Turn
"strops"into"sports". - Turn
"racecar"into"racecar".
Bonus
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.
