1. Real life: where you meet this problem in daily life.
2. Logic: the idea in 2 to 4 simple steps, before any code.
3. Code: a complete program you can copy and run.
4. Output: the real output, with the input typed.
5. How it works: the key lines, explained in one or two short sentences.

Try each program yourself first. Then open the solution and compare.
