Introduction to Functional Programming, exercises

Getting started

Clone this repository by running

 git clone https://github.com/opqdonut/ifp2018-exercises.git

Change directory to the cloned repository
```
 cd ifp2018-exercises
```
Download dependencies by running
```
 stack build
```
Then check you can actually run the tests with:
```
 stack runhaskell W0Test.hs
```
This should print Everything seems to be OK!. If you see any errors, you might have a problem with your Haskell installation.
Now you can edit W1.hs and see how well you did by running
```
 stack runhaskell W1Test.hs
```

Edit the Wn.hs files according to the instructions
Don't remove or change any type signatures (things like foo :: String -> String) that are already in the files
Check your answers for week n with stack runhaskell WnTest.hs (or just runhaskell WnTest.hs if you're not using stack)
A typical test failure looks like this:
```
  Testing 11
  *** Failed! Falsifiable (after 1 test):
  0
  0
  Expected 1, got 3
  FAIL
```
This means that the function from exercise 11 failed the test when the two arguments were 0 and 0. The result should have been 1, but it was 3.

I'm sorry if the test failures aren't always understandable :/

You can also play around with your solutions interactively by running stack exec ghci Wn.hs (or ghci Wn.hs). This is a good idea for instance when you don't understand the test failures.
Use the :reload command to reload the file if you've made changes.
You can use the :type command to get the type of an expression, for example :type tail "asdf"
