Imagine you have a friendly robot puppy that wants to reach a tasty bone across the room. How can you tell the puppy exactly where to walk?
We can draw a map made of square tiles called a grid, and use arrows to show each step.
Every arrow is a single command: one arrow moves the character one square in that direction.
What happens when we string several arrows together to make a full path?

Building a Sequence

An ordered list of steps to solve a problem is called an algorithm or a sequence.
To guide our puppy to the bone, we read the arrows from left to right, one by one.
The sequence Right, Right, Down, Down moves the puppy four times to reach the bone safely.
A common mistake is counting the starting square as your first move. Remember: you only count a move when you step into a new square!
What if a big mud puddle is blocking the path?
