Python Pathway - From Zero to Competitive Python - Volume 4: Competitive Algorithms (Thuat toan thi dau)

This is the fourth and largest volume of the Python Pathway series, written in Vietnamese, deploying the full spine-cluster architecture at competition intensity. Across eleven chapters it activates all nine algorithm clusters (S1 through S9): a focused contest reading-and-triage chapter, smart enumeration, greedy methods with exchange arguments, a heavyweight dynamic programming chapter, shortest paths and minimum spanning trees, advanced tree structures (Fenwick and segment trees, LCA), string processing (KMP, Z-function, hashing), composition, disguised-problem recognition, full mock contests with post-mortems, and an IOI-style subtask-scored project. Every cluster is exercised across all four transformation axes at once, with each topic taught in solve, recognise, and adapt variants. Aimed at students on the Vietnamese national-olympiad pipeline who completed Volume 3, it functions as a disciplined practice room, all code in Python, distinct from the companion From Scratch to Python volume.
