How write third problem shortly ? I have very long and wrong solution.
Since sx < tx and sy < ty, it is trivial that first to-and-fro path is going to be a rectangle with (sx, sy) and (tx, ty) as opposite vertices.
The second to-and-fro path is around the same rectangle, taking four extra edges, effectively :
So answer is coordinates of two rectangle ? Second rectagle is bigger than first?
Doesn't matter which rectangle you trace first.
Ok. But one rectangle is bigger than other?
Yes
