This subcategory is for Groovy programmers. Don’t be shy, no question is too simple or too complicated.
Please, do not post here if your question is about a puzzle, a contest or anything that relates to the CodinGame platform (there are other categories for that purpose).
Is Groovy bugged somehow? I tried it a few times and as soon as the code is getting a bit more complex (using multiple inner classes) the code stops working on really strange things (like
def a = []
println a
breaks, because a is not defined (a.length doesn’t work too, a.push(1) too)
