🧠 Logical Programming Problems is the complete English-language guide to a curated collection of logical and algorithmic problems for developers who want to sharpen their thinking. Learn classic puzzles, recursion drills, dynamic programming patterns, graph problems, and interview-style challenges — each with clean explanations and Python solutions you can run today. Built for students, interview candidates, and self-taught developers. Completely free. No signup. No paywall. No hidden chapters.
Most problem collections are just answer keys. This guide explains the thinking — how to break a puzzle into cases, how to spot DP overlaps, how to prove your recursion terminates. Every problem ships with a pattern label, a solution, and a short "why it works" note.

|
| Step | Action | Time |
|---|---|---|
| 1 | Pick a category | ~1 min |
| 2 | Read the problem | ~3 min |
