2-3 Tree

Python interface for a 2-3 tree integer store, implemented in C.

Requirements

Build .so file:

python3 setup.py build

Locate the .so file that is generated, and move it up to the working directory:

mv build/lib.linux-x86_64-3.5/Tree.cpython-35m-x86_64-linux-gnu.so Tree.cpython-35m-x86_64-linux-gnu.so

Instantiate twoThreeTree object with optional array of initial integer values:

from twoThreeTree import twoThreeTree

myTree = twoThreeTree([1,2,3])

Check for presence of integers:

myTree.contains(1) # True
myTree.contains(0) # False

Insert additional single values:

myTree.insert(0) # True
myTree.contains(0) # True

Remove values:

myTree.remove(1) # True
myTree.contains(1) # False

Get number of leaves in tree:

myTree.count() # 3
