Study Notes
Understanding Algorithms
- An algorithm is a set of instructions for solving a problem.
- A recipe for baking a cake is an example of an algorithm.
- It is important to write algorithms with clear and simple steps.
- Checking an algorithm ensures it has the right answer.
Correcting Algorithms
- A bug in an algorithm is a mistake in the instructions.
- To correct a bug, change the wrong instruction.
Creating with Scratch
- Scratch is a tool for creating animations and games.
- A sprite is a character or object in Scratch.
- Motion blocks in Scratch make a sprite move.
- The "wait" block in Scratch pauses the animation for a certain amount of time.
