LeetCode problems, but make it for Program Analysis, Transformation and Code Generation (PATCG).

I got bored of grinding LeetCode like everyone else. I love PATCG, the beautiful, brutal world of compilers, JITs, GCs, linkers, and everything that actually makes code run.

So I did the only logical thing: took 100+ LeetCode problems and mapped each one to its natural systems counterpart.

What you'll find here

Every classic LeetCode problem re-imagined as a real systems programming challenge:

• Two Sum -> Symbol table resolution / constant pooling in the linker
• Trapping Rain Water -> Heap fragmentation & GC compaction
• Merge K Sorted Lists -> VTable / MRO resolution
• Course Schedule -> Circular dependency detection in module loading
• ...and more

Made with pure boredom + love for PATCG.
