Scratch Practice Drills (スクラッチ練習ドリル)-AI-driven coding drills

Introduction to Scratch Practice Drills (スクラッチ練習ドリル)

Scratch Practice Drills (スクラッチ練習ドリル) is designed as an educational tool to help beginner to intermediate-level programmers practice and refine their coding skills, particularly in Scratch or entry-level programming languages. The drills are inspired by problems found in competitions like the Information Olympiad and the Pasona Koshien, which are targeted at high school and early university students. The exercises focus on simplicity, ensuring that solutions can fit within a single screen, promoting clarity and making them ideal for novice coders. The goal of Scratch Practice Drills is to provide a structured pathway for learners to gradually progress from basic concepts to more advanced problem-solving techniques. This gradual approach is reflected in the drill’s difficulty levels: Introduction (入門), Beginner (初級), Beginner II (初級II), Intermediate (中級), and Advanced (上級). This makes it a suitable resource for people just starting with coding as well as those preparing for entry-level programming competitions. Additionally, the practice problems are offered in multiple languages to accommodate different learning preferences and include a friendly, conversational tone to make learning more approachable. **Example:** A typical beginner drill might ask the user to create a basic program that prints the sum of two numbers. For more advanced learners, the tasks would involve implementing small algorithms, such as sorting a list or solving a simple mathematical problem like finding the greatest common divisor (GCD).
