I live in Lom Talay village. It is called a village, but is just a guarded set of houses laid out in a square grid. ‘Housing complex’ would be a better term, but not as appealing.

As I was sitting in the village’s park I observed the garbage truck visiting all the houses and the following problem was discovered.

A garbace truck enters a village at A and leaves at A. How many squares does it have to cover to visit all the houses? Another way of saying the same thing: How long unbroken line is needed to draw a 2×2 square grid when you start and end in one of the grid’s corners?

When you have the answer for 2×2, have a go at 3×3, and nxn.

Now imagine that our village has a triangle layout:

Answer the same questions as for the square grid.

Far from idleness being the root of all evil, it is rather the only true good. - Søren Kierkegaard
