Problem Description

The file readme.md is the description students read when they open the problem. It's shown next to the code editor.

Format

Write it in Markdown. If you don't know Markdown, here's the basics:

# Big heading

## Smaller heading

Normal paragraph text.

- Bullet point
- Another bullet point

**Bold text** and _italic text_.

`code like this`

    code block
    (indent with 4 spaces)

Example

# Add Two Numbers

Write a function called `add` that takes two numbers and returns their sum.

## Example

add(1, 2)  → 3
add(5, 5)  → 10

## Rules

- You cannot use any libraries
- Your function must be named exactly `add`

Tips

  • Keep it short. Students are there to code, not read.
  • Show an example or two. It's easier than explaining in words.
  • Tell students exactly what the function should be named.
