The problem is, how many routes can one take to get to point A to B without backtracking?
I know that I can solve this by assigning numbers to the intersections and that the intersections add up. However, I got stumped at certain parts because of the two rectangles. I might have also gotten some parts wrong. I also know that I can utilize combinatorics but I am not exactly sure how since there are rectangles.
Any help is appreciated. Thank you!
