Do not vandalize your own kata, even when it got retired.

You're right about all of this; I made this because I was bored in class and didn't really stop to think about anything. Thanks.

Issues:

• 100k tests is overkill, and ~100 should be totally enough.
• It is not clear if collinear points are a valid triangle. What is expected answer for [ [0, 0], [1, 1], [2, 2]]?
• Text like "Code should identify invalid arrays." should be a title of a test case or a test group. Assertion message should present input of a failing test.
• Tests should specify and validate requirements w.r.t. mutation of input array. In this problem it is not necessary to mutate the input to solve it, so I think that specifying mutation as forbidden (and enforcing this) would be a way to go.

Suggestions:

• (int) (Math.random() * 200) -100 is a really bad way if generating random numbers. There is Random::nextInt, there is Random::ints.
• Solution class could use some less specific name than ForemanPig.
• Logic for generating dupes seems very convoluted. It can be significantly simplified, and dupes should be guaranteed to occur in the test set, and not be present only by random chance.

• Messages are not formatted correctly:

For input: [[I@1ffe63b9, [I@51e5fc98, [I@51e5fc98, [I@7c469c48] ==> expected: <true> but was: <false>

• Only some tests attempt to present inputs, while some others do not.

I read the description a couple of times and I still have no idea what "ordered pairs" are, especially in context of triangles :thinking:

I edited the description; thank you.

A minor typo in the description:

... the 1st character of the ou[T]put is the average ...

looks good!

fixed, thanks!

Something seems off with the C random tests. For example:

This was happening because you were mutating the input, which causes unexpected behavior. I have fixed the code so this will not happen any further. Please click RESET in your trainer (don't forget to copy your code if you don't want to lose what you do have), and you will notice that the declaration is now: void decipher(size_t length, const char * const code[length], char *mew).

Thank you and good luck!

I get a SIGABRT with my code. Surely, my code is wrong but I do not allocate any memory so how is it possible?

Besides, I'm seeing

Expected: "*&ikh)ihg&j'kj%&hij'-&'*ih)h'"

which should not be possible ("Every String consists of only lowercase letters and spaces.")

Thank you!

C Translation

... Easy fix... =_=

Thank you for bringing the issue to my attention, if it still doesn't work come yell at me
