Workshop, list manipulation in Haskell

Objective

Reimplement functions from the standard library, more precisely functions to manipulate lists.
You can use all functions except for the one you are implementing (can't use length to implement myLength).
You will find the functions to implement in the src/ directory.
You can use tests to get a quick description of every function.

There are 6 files of increasing difficulty:

• Basic
• Easy
• Medium1
• Medium2
• Hard
• Bonus

Try to do them in that order.

Testing

You can use the 'test.sh' script to run tests to check if your implementation is correct.

This script can be used in 3 ways:

• 0 arguments: Runs all tests
• 1 arguments: Runs a part of the tests corresponding to a level of dificulty
• 2 arguments: Runs tests for a specific function in a level of difficulty

For example:

• ./test.sh will run all tests
• ./test.sh Basic will run tests on basic functions
• ./test.sh Basic myNull will run tests for the myNull function

You're probably going to want to test function by function, the test output can be pretty obnoxious.

Notes

Some prototypes have been simplified.
Error handling is not required.
You can create helper functions.
