See the note below.
Let's consider the following output:
5 1 50 2
8 1 80 2
This output is not guaranteed to catch the thief and is not correct. It is given to you only to show the expected output format. There exists a combination of an initial position and a movement strategy such that the police will not catch the thief.
Consider the following initial position and thief's movement:
In the first hour, the thief is located in district (1,1). Police officers will search districts (5,1) and (50,2) and will not find him.
At the start of the second hour, the thief moves to district (2,2). Police officers will search districts (8,1) and (80,2) and will not find him.
Since there is no further investigation by the police, the thief escaped!
