This is a beautiful solution.

.

the kata is now too old to change things like that (too many translations)

it's outside of the requirements.

not ideal, but not really a problem either. Moreover, considering how old the kata is... Closing.

done (that was about the sample tests only)

if the requirements are saying that the input is in between 1 and 100 both inclusive, don't expect inputs to be somewhere else. ;)

any solution for this ?

I'm not sure what you expect then... 1 ≤ w ≤ 100, that's what the tests generate.

Shouldn't it be in all the languages?
"Task: Given an integral number of watermelons w (1 ≤ w ≤ 100; 1 ≤ w ), check whether Pete and Billy can divide the melons so that each of them gets an even amount."
In the test cases, it only verifies up to 100.

Which language?

In the instructions they give (1 <= w < 100). Isn't there a problem with the test cases? There is no comparison for anything higher than 100.
