Description
There is a thief (T) and a detective (D) as shown in the grid above. To catch the thief, the detective can move from one square to a square next to it either vertically, horizontally, or diagonally.
However, the detective must change his direction every time he moves one square. For example, if the detective has just moved diagonally north-east, then his next move cannot be diagonally north-east.
The thief does not move, and the detective catches the thief by ending up on the same square as the thief.
The detective needs to collect gold coins the thief has dropped from as many of the squares as possible.
