i managed to do it (or thats what i think), the tree apparently works, but i dont know if its balanced, can you have a look at my code? i want to know if my tree is balanced correctly, here is the code: https://pastebin.com/ineG07b2 (PS: im aware that this code doesnt guarantee that the root will be black, the wikipedia article says that the black root is not a strict requirement by all the authors, so i decided to omit that)
