    Great Kata!

    Fun :-) Is there a part 2?

  • Ob1ivion Avatar

    How first answer of is equal to (0,1)? Isn't it (1,0)?

    Describe(exit_from_maze_tests) {
  It (passes_example) {
    Board m {
      "##############",
      "#        \\   #",
      "*   \\        #",
      "#            #",
      "#   \\    /   #",
      "##############"
    };
    Assert::That(exit_from_maze(m), Equals(Result({0, 1}, 22)));
  }

    The same second example: it should end on (5, 7)! how it is (6,4)?

     It (passes_second_tests) {
    Board m {
      "###*###",
      "#/ /  #",
      "#     #",
      "#     #",
      "#\\    #",
      "#######",
    };
    Assert::That(exit_from_maze(m), Equals(Result({6, 4}, 10)));
  }
};

    I am totally confused, with how answers have gotten? Can you explain me, please!

    Fixed C compiler warnings ;-)

    I don't see any mentions of the order of the position property: which one is the x direction and which one is the y direction?

    It's a decent kata, but I agree with @JohanWiltink's comment. It's a familiar challenge, essentially a simpler version of my Ziggurat ride kata.

    I'd have ranked it higher but for the task not being new. Maybe it's new in C, in JS it's not. I don't know if it's really an issue, but this feels like more of the same old same old. Looking forward to new parts though, hope they do bring newness ( newity? ).

    ^ here's a javascript translation :)

    It's never mentioned that when * doesnot exist, {{-1,-1},0} is expected

     passes_fixed_tests
Expected: equal to [unsupported type]
Actual: [unsupported type]

    This is not debuggable, please change to another type (maybe a simple std::vector<uint64_t>), or you will need to construct your own debug message

    using uint  = unsigned int;
using Pos   = std::pair<uint, uint>;
using Model = std::vector<std::string>;

    Test cases should not relay on these definitions cause users can modify them easily
