The lawn mower on a field.
Implementation of a solution according to the specifications.

Possibilities to implement the main solution are :

• Adding a main class reading from a file path or a string.
• Having a Web Service implementation supporting a string or a binary file.

According to the subject test data :

• Case 1 works we have the result X=1 Y=3 O=N
• Case 2 doesn't work we get X=1 Y=5 O=E instead of X=5 Y=1 O=E

Possible extensions to the solution are :

• Taking into account the position of the mowers on the field with the observer when moving mowers.
• Save the history of a mower movement position to simulate the movements on an IHM.
