πŸ“š Quick Study Guide

  • πŸ”’ What is a Sequence? A sequence is a list of instructions that a computer follows in order, one after another. Think of it like a recipe!
  • πŸ•ΉοΈ Why are Sequences Important? Computers need clear instructions to perform tasks. Sequences ensure the computer knows exactly what to do and when to do it.
  • ✏️ Examples of Sequences: Brushing your teeth (wet toothbrush, apply toothpaste, brush teeth), making a sandwich (get bread, add fillings, put bread together).
  • πŸ’‘ Debugging Sequences: Debugging means finding and fixing errors. In sequences, check that the steps are in the correct order. What happens if you put the bread *after* the fillings?
