Non-deterministic spec tests for question 2A on the re-exam

Unfortunately, it seems the spec tests for the function
overlapfor question 2A are not entirely deterministic. After the exam, we will re-run all spec tests with a fixed seed so that every solution is evaluated in the same way. In the mean time, please re-run the tests one or two times to make sure your solution is correct.
Update: I have changed the spec tests so they are now hopefully more reliable.
Fixed deadline for the project

Ignore the message below, I got confused twice. The deadline has passed indeed. Sorry about this.
I got confused by the weblab interface starting the week on Sunday and set the deadline for the project submission on 16th instead of 17th.
It’s fixed now, but just so really no-one misses it it’s on on 18th at 12:00 (noon).
Project, spectest changes

For the project we found one number test which was incorrect and is now fixed. Some students also had problems with the recursive descent tests only getting one succesfull test. This problem should now be fixed.
Question 3: Data Structures small typo fixed

The description used to say
“bags of elements of elements of type a”.
It has been amended to say
“bags of elements of type a”.
Question 5: Laziness had been fixed.

There was a typo in the second case of the definition, it said
lookup n (x:xs) = x
Now it says
lookup 0 (x:xs) = x.
Sorry about it.
