Lua:

Random tests always (as in 99% of the time) return non-square numbers

Why return c() for input integer(0) don't work in R?

c# translation

There is a mistake in random tests in ruby. In one point it's expected the code to pass with really big numbers, over 2 billions, at second poing it's expected to return nil for number over 1 billion becouse its to big number.

nitpick: a minor typo in the decsription check whet[H]er a given

A little disappointing that the tests are so undemanding. Even the very naive solutions can pass.

What is the maximum possible value for "n"?

Similar to this issue but in Python:

Assertions are placed in conditional blocks what causes that they are sometimes not executed, making test output incomplete.

In python, you should forbid the ** and pow operator, because naive solutions, that similar to me, pass.

C#: TestUpTo500 can be passed with a solution which returns any incorrect answer, for example (0, 0).
