Introduction to Scala Academic Project. Work done with my team mate Louis Grunenwald.

Explanation in the code will be in French.

Features

This Scala program implements an automatic lawn mowing for rectangular surfaces.

• Each mower can be programmed to cover the entire surface.
• The position of the mower is represented by a combination of coordinates (x, y) and a letter indicating the orientation according to the English cardinal notation (N, E, W, S). The lawn is divided into a grid to simplify navigation.
• To control the mower, we send him a simple sequence of letters. The possible letters are "D", "G" and "A". "D" and "G" rotate the mower 90 ° right or left respectively, without moving it. "A" means that the mower is moved one step in the direction it faces, and without changing its orientation.
• If the position after movement is outside the lawn, the mower will not move, keep its orientation and process the next command.
• Each mower moves sequentially, which means that the second mower moves only when the first mower has performed its entire series of instructions.
• When a mower completes a series of instructions, it communicates its position and orientation.

Input file

To program the mower, it is provided with an input txt.file built as follows:

• The first line corresponds to the coordinates of the maximum if the loans, for example (5,5), so we will have a matrix with the following coordinates (0,0) - (5,5)
• Each mower has two lines: the first line gives the starting position of the mower, as well as its orientation.
• The position and orientation are provided in the form of 2 digits and a letter, separated by a space the second line is a series of instructions ordering the mower to explore the lawn.
• The instructions are a sequence of characters without spaces.
