I\'m passing an interview in one week and I need some resources to get the "parctical theory" of the Tree data structure. By "parctical theory" I mean resources that don\'t dig too deep, just enough to solve 80% of the related leetcode Tree problems and resources that go beyond the definition of a Tree. I\'m looking the sweet spot.\n\nI don\'t mind the format: YT videos, book chapters, blog post, SO questions ...\n\nThank you very much :-)
