Recursive_algorithms

Learn the concept of recursion, a technique that is often used in algorithms. See how to use recursion to calculate factorial and powers of a number, plus to generate art.

Intro_to_algorithms

What are algorithms and why should you care? We'll start with an overview of algorithms and then discuss two games that you could use an algorithm to solve more efficiently - the number guessing game and a route-finding game.

Quick_sort

Learn quick sort, another efficient sorting algorithm that uses recursion to more quickly sort an array of values.

Further_learning

Ideas of how you could continue your learning journey in algorithms.

Towers_of_Hanoi

Use the recursive technique to solve the Towers of Hanoi, a classic mathematical puzzle and one reportedly faced by monks in a temple.

Breadth_first_search

Learn how to traverse a graph using breadth-first-search to find a particular node or to make sure you've visited all the notes, traversing one layer at a time.

Insertion_sort

Learn insertion sort, another simple but not very efficient way to sort an array of values.

Binary_search

Learn about binary search, a way to efficiently search an array of items by halving the search space each time.

Merge_sort

Learn merge sort, a more efficient sorting algorithm that relies heavily on the power of recursion to repeatedly sort and merge sub-arrays.

Selection_sort

Learn selection sort, a simple algorithm for sorting an array of values, and see why it isn't the most efficient algorithm.

Asymptotic_notation

Learn how to use asymptotic analysis to describe the efficiency of an algorithm, and how to use asymptotic notation (Big O, Big-Theta, and Big-Omega) to more precisely describe the efficiency.

Graph_representation

Learn how to describe graphs, with their edges, vertices, and weights, and see different ways to store graph data, with edge lists, adjacency matrices, and adjacency lists.
