Binary Search Trees Code

Python implementation of Binary Search Tree code from "Introduction To Algorithms"

This is the code for the presentations on Binary Search Trees in January/February 2020.

Usage

This code is really intended to be used interactively. For example, I loaded it into PyCharm, launched the Python console and then would use it as follows (the '>>>' is the Python REPL prompt):

>>> from app.ops import *

>>> t1 = create_tree_from_list([15, 5, 16, 3, 12, 20, 10, 13, 18, 23, 6, 7])
>>> tree_print(t1)
3
5
6
7
10
12
13
15
16
18
20
23
>>> tree_delete(t1, 5)
...

Supported Functions

If you look at ops.py, you'll see that I've implemented the basic functions to create trees, search them, print them, as well as adding and deleting new nodes in the tree.

CAVEAT EMPTOR

There is currently a bug in master that causes tree_delete not to work in certain circumstances. The example above, `tree_delete(t1, 5) demonstrates this bug.

I encourage people to fork & submit PR's to fix this bug. If you're really stumped, I will be publishing a fix for it soon. :)
