Elementary maths in numeric bases
Base change related problems make for good puzzles.
A first brush with DAWs and LMMS
I’ve always wanted to be able to make music, something at least, and now with LLMs venturing into such unknown territories has become so easy.
Binary Lifting
The core idea of the whole process is intuitive to me so I’ll just leave some implemeational comments on stuff and doubts while writing.
Decompositions
pre-requisites the idea of such decomposition algorithms on trees is that any “breaking” you do, for a reference pair of nodes (u,v) they will be in ONE component until some specific node c, splits them into different ones.
Edge message dp on trees ( aka Re-rooting )
Think of this when you can answer something for a node you and want to answer the same for every node.

Chapter 2 - Basics I think the initial chapters are REAAALY jargon heavy for no reason linear mappings these are the same as the scalar mappings which basically ASK something about the vector but in this case they map to a diff vector space which is fine ig, more generalised for example R^2 ⇒ Comple...
