This resource offers a total of 30 Python Binary Search Tree problems for practice. It includes 6 main exercises, each accompanied by solutions, detailed explanations, and four related problems. [AnEditoris available at the bottom of the page to write and execute the scripts.] ...
Some of the problems and puzzles below should be their own repos because of their size, but the convenience of a single binary tree package is too great to break them out.BuildingSupport code resides entirely in package tree, which lives in the tree/ directory. Answering the questions or ...
Practice implementing recursive solutions for traversals and other tree problems. Know your traversals: In-order, pre-order, post-order, and level-order traversals each have their strengths and applications. Understand when to use each and how to implement them both recursively and iteratively. ...
A complete binary tree is efficiently implemented as an array, where a node at location (i) has children at indexes (2*i) and ((2*i) + 1) and a parent at location (i/2). This is also known as heap and is used in the HeapSort algorithm; we will get to that in a little ...
