May we ignore "Warning: calling polyEqual" warnings? | |
|
Yes. This warning doesn't indicate any real problem with the code. You can also try turning these warnings off with the command: "Control.polyEqWarn := false" |
In question 7c, what do you mean by saying that "two types match" (טיפוסים תואמים)? | |
| Two types match if they are equivalent or if one is a subtype of the other. |
In question 5, what should return when we call getPaths with the same source and target node? | |
|
There is only one simple path from 'v' to 'v'', which is the path [v]. In the example from the PDF, if we write 'getPaths E 2 2', the answer is [[2]]. |
When we call some of our functions with an empty list, we get a message like: | |
|
ML gives you this warning when you call a polymorphic function with a polymorphic parameter. You can read more about this at the end of tutorial 3. For assignments in this course, you may ignore these warnings. |
Hint for question 7c: | |
| Read about "Interface types" at the Go language specification. |
Do we have to use tail recursion for question 5? | |
| No, you don't. |
