❔ guys please help me with AVL Trees
I have a project where I need to create a box object using a data structure that will be most efficent to store boxes insert, delete, search for exact match
and if no exact match search for closest bigger > than searched box I am trying to use a AVLTree, That store another AVL tree in case there is duplicates
and in the duplicated it should be sorted by Y instead of X in the main AVLtree I was wondering if there is a way to see it visualy instead of using debug

or help me to suggest the mst efficent data structure to use
any help would be much appreciated
