TSPHeuristics

LinkedListRecursionSort

Wrote an algorithm that recursively sorts a linkedlist in Java. Not the most efficient, but a good exercise

LinkedListRecursionAssembly

Wrote a recursive LinkedList in Assembly, ARM-based

StringProcessingAlgorithm

Dynamic Programming. Process and Space words from a dictionary.

MedianofMedians

Implemented Quickselect with Median of Medians running in O(n) time in the worst case, optimized from a method like Collections.sort on the large array of size n/5, since the runtime of that algorithm is Ω(n log n) in the worst case.

AssemblyRecursion

Implemented this in ARM:

BubbleSortAssembly

Bubblesort Algorithm in Assembly for ARM

Weighted-Undirected-Graph

Implementation of a Weighted Undirected Graph with Prim's Algorithm

Self-Balancing-BST--Randomized-Tree-Set-and-BST-Sort

Multiple Sorts with Runtime Analysis and Splay Rebalancing in BST

Eulers-Algorithm-using-Assembly

Java based Assembly for ARM. Euler algorithm for determining the Greatest Common Divisor (GCD) of two numbers A and B without using a division operation.

Ternary-Heap-and-Median-Heap

Curious if I could use Max-Min Heaps to create a Heap that could easily produce a median for me in a dataset efficiently, without the use of linear search/binary search using knowledge of Data Structures. Ternary heap is a heap with every parent having 3 children. Included test cases for the MedianHeap.

Simple-Assembler

ARM processor. Assigning Variables in Java-based Assembly, including using Arrays and a basic LinkedList

BST

Binary Search Tree with methods: height(), size(), put(Key key, Value val), delete(), and printBSTinOrder()
