Homework 5

[Filip Boltuzic]

Few questions about the homework part

1. In the example of instructions "RAALAL" how to end up in (9, 4) West. I keep ending up at (9, 5) West. My logic from start (7, 3) North

a) R -> (7, 4) East

b) A -> (7, 5) East

c) A -> (7, 6) East

d) L -> (8, 6) North

e) A -> (9, 6) North

f) L -> (9, 5) West

2. Some triangleTypes overlap. Triangles that are Degenerate can be also Isosceles (side lengths of 2 2 4), as well as Scalene (2 4 6). What to return in this case?

When you turn left or right, you don't move, you just change your bearing.

I also have a question regarding second problem.

It says we have to create data type Triangle, but function triangleType doesn't accept Triangle, just numbers. Is that an error or do we have to write another function that accepts Triangle but delegates to triangleType?

[Filip Boltuzic]

I believe inputs to construct a triangle are side lengths.

Doesn't the Degenerate case take precedence? Because every degenerate triangle is either Isoceles or Scalene; them having precedence over Degenerate wouldn't really make sense.

Nikola already answered the first question. When you turn your direction, you stay in the same place.

Second question: Degenerate triangles are the most precise description of that triangle. It takes a higher priority.

[Jasmin Zukić]

I made a mistake with the Triangle. It should be data TriangleType instead of data Triangle.
