Welcome to the "Build Letter E" challenge!

Let's recap the ninja methods and features you've learned:

Ninja Methods:

• go_right(), go_left(), go_up(), go_down(): Move the ninja one cell in the specified direction.
• pick_sushi(): Pick up sushi from the map and add it to your inventory.
• put_sushi(): Place sushi from your inventory onto a cell.
• object_up(), object_down(), object_right(), object_left(): Determine the object in the next cell in the specified direction, returning "wall", "sushi", or "empty".

Programming Concepts:

• Functions: Create reusable blocks of code to perform specific tasks.
• Decomposition: Break down complex problems into smaller, manageable parts.
• Loops: Use for and while loops to repeat actions.
• Conditional Statements: Use if-else statements to make decisions based on conditions.
