Distance between two points on a gridline

This exercise finds the distance between two points that lie on the same gridline — they share either their x-coordinate or their y-coordinate. When two points share a coordinate, you can just count the squares between them, or subtract the coordinates that change.

What does this generator do?

Picks two points in the first quadrant that lie on the same horizontal or vertical line and asks for the distance between them.

How to use it

If the y-values match, the distance is the difference of the x-values. If the x-values match, it is the difference of the y-values. Subtract the smaller number from the bigger one.
