While sorting seems like a fairly intuitive process to us, it’s rather involved for computers! In this series, let’s delve into how computers perform sorting, studying all the classics like Bubble Sort, Quicksort and Mergesort, while also picking up key computing skills like Recursion and Time Complexity!
In addition to the basic Sorting Algorithms discussed above, more complex algorithms exist, making use of specialized Data Structures to get the job done efficiently! This series delves into data structures like Balanced Binary Search Trees and Binary Heaps.
Graphs are one of Computing’s most powerful data structures, capable of modelling problems in predictable and efficient ways. In this series, we delve into what graphs are, and what algorithms we can perform on them. From simple breadth / depth first search to more complex ideas like pathfinding with Dijkstra’s Algorithm and Topological Sorting. We’ll also take a closer look at Dynamic Programming in this series!
Logic Gates form the basis of much of computation today. In this series, we delve deeper into how the different types of logic gates behave, and how they can be combined to create more complex components like Encoders, Multiplexers, and Flip-Flops!
Delving even deeper past Logic Gates, we study the components that make them work – The transistors inside! In this series, we study how NPN and PNP transistors are used in circuits. We’ll build logic gates and other components like a Bistable Multivibrator and a Pulse Detector using transistors and capacitors.
We take a closer look at SQL, the Structured Query Language, a declarative programming language used to interact with databases. In this short series, we look at the operations that can be performed on a database and just what makes databases so powerful!
