Let's try add sine waves together and see what sort of sounds we can create!

What do the Rubik's cube and a cipher from the 70s have in common? Let's find out.

If you played the game perfectly, could you always win a game of Tetris? Or is there some sequence of blocks that could force you to lose the game, no matter how good at the game you are? Here, we take a look at some of the mathematics behind a theoretical game of Tetris and reason through whether it's possible to win.

What are tensors? How do they differ from matrices? And why do we need tensors in the first place?

Problem Description

https://leetcode.com/problems/add-two-numbers/description/

Algorithm Description

Solved by simulating digit-by-digit addition with carry logic, represented through animated Linked Lists.

Complexity Analysis

Time Complexity: O(max(m, n)) — we iterate through the lengths of l1 and l2, where m and n are the number of nodes in each list.

Space Complexity: O(max(m, n)) — the length of the new linked list is at most max(m, n) + 1.

What exactly is a tensor?

Dan Fleisch briefly explains some vector and tensor concepts from A Student's Guide to Vectors and Tensors

This video series visualizes tensors using a unique and original visualization of a sphere with arrows.

We will cover how to create a recursive formula for the Tower of Hanoi issue. After we've found it, I'll show how to find a closed formula and proof it with the help of induction.

This full course provides a complete introduction to Graph Theory algorithms in computer science. Knowledge of how to create and design excellent algorithms is an essential skill required in becoming a great programmer.

In this video we introduce and analyze the running time of the selection sort algorithm.

A sort visualizer from scratch in C++ using SDL2. This visualizer with mild tweaks can be used on any sorting algorithm.
