Leetcode Visualized: Number of Islands - Typescript - LC200

A 3D visualization of and solution for Leetcode problem 200 (Number of Islands) in Typescript.
This was an experiment to see if applying 3D animation to Leetcode problems makes them easier to understand and remember. Please let me know if you'd like to see more like this in the comments.

- Corrections -
* at 3min40s, the algorithm may actually quickly repeat a few times more than 2 as it checks each tile's neighbors, which may overlap
* at 4min38s, the first array is rows, not columns; more reason to double-check confusion during interviews.

- Colophon (how I made this) -
The writing was done in Notion (in a spreadsheet b/c I'm a weirdo).
Storyboards were drawn by hand with pen and paper.
3D Illustrations were animated in Autodesk 3ds max 2023.
3D textures were edited/painted in Adobe Substance Painter.
3D images were rendered using Arnold (took ~45 hours).
2D graphics were composited and animated in Adobe After Effects.
Camera: (amzn.to/3Py0KdL)
Lens: Tokina 25-75mm T2.9 cinema lens.
Recorder: amzn.to/3G52Du6
Microphone: amzn.to/3yPxIjF
Audio Interface: amzn.to/3NqoQ8j
Two hours of video footage were reduced to 12 minutes using Vidbase AI.
The final video was edited in Adobe Premiere Pro.
