This is a classic property of triangles one would encounter in elementary school, if not, the results are also easily searchable, so not a kata issue! And giving away too much hints will just make the kata a trivial 8kyu anyways.

kata hint != kata suggestion

One of the properties of triangle is:

The sum of the length of two sides is always greater than the length of the third side

You can experiment it yourself though. Like take a piece of ruler and measure corresponding matchsticks that you would cut into pieces, then see if they can form a triangle by matching their edges together.

Because when you have sticks with lenghts of 2 inches, 3 inches, and 4 inches, you can build a triangle out of them. But you cannot build a real triangle with sticks of lenghts 1 inch, 2 inches, and 3 inches.

I am not sure I understand the problem completely! Why is "4,2,3" expected to be "true" and "1,2,3" false?

That was a poorly worded `issue` posting.

• be specific about what exactly you think the problem is
• give examples
• if possible, offer a solution

This is really a purely worded Kata.

The "detailed requirements" part is an outright spoiler tho. It totally strips the problem out of the problem, and all what is left is typing in a bunch of characters. I think it goes too far.

One issue I see is that negative inputs can be surprising: they are not mentioned in description, and solutions which just implement the triangle inequality theorem can get them wrong. IIRC, some languages also have inputs which trigger overflow. At the very least, ranges of inputs should be specified. Otherwise it's just getting surprised on every ATTEMPT with some new type of input.

severely?

• hey, check out these 3 numbers
• can they form a triangle?

... why?
