Giles has asked Buffy to optimize her procedure for nighttime patrol of Sunnydale. (This takes place sometime in Season 2.) Giles points out that proper slaying technique would allow Buffy to traverse all of the streets of Sunnydale in such a way that she would walk on each side of each street, exactly once, going up the street in one direction and down the street in the other direction. Buffy now has slayer homework: how can it be done? (If you have to assume anything about the layout of the city of Sunnydale, make it clear!). Use either C, Java, or Python
