CP4CPP

Purpose

CP4CPP is an educational infrastructure for competitive programming in C++. It preserves scattered notes, editorials, implementation tricks, visual experiments, and practice workflows as one maintainable system.

The project treats knowledge as a graph: each concept is a node, each problem is an edge, and learning means choosing useful paths instead of only increasing solved count.

React Flow

Press enter or space to select a node. You can then use the arrow keys to move the node around. Press delete to remove it and escape to cancel.

Press enter or space to select an edge. You can then press delete to remove it or escape to cancel.

MICRO Standard

Letter	Rule	Meaning
M	Minimal	Keep only content with clear value, scope, and reason.
I	Interactive	Support feedback, exploration, or useful action when it improves learning.
C	Consistent	Terms, hierarchy, tags, formats, and design rules must not fight each other.
R	Readable	Material must be understandable by normal readers, not only strong experts.
O	Optimizable	Every part should remain improvable, reusable, refactorable, and not badly locked.
