• Commands are case-sensitive

Scenario 1: No collision - single rover

Welcome to Mars Rover program!
Enter Command for Rover in format:
1: <Rover number> <Co-ordinate X, Y, Direction (E, W, N, S)> <Movements (f, b, l, r)>
2: Q to quit
3: S to get Rover positions
1 3,4,N f,f,r,f,f

Enter Command for Rover in format:
1: <Rover number> <Co-ordinate X, Y, Direction (E, W, N, S)> <Movements (f, b, l, r)>
2: Q to quit
3: S to get Rover positions
S

Rover 1 position:
Final Coordinate: 5,6
Final Direction: EAST

You can follow above command to control the same rover by number.

Scenario 2: Collision with rovers on initialization

In case of rover being initialized on a position that conflicts with another, it won't be initialized

Limitations

• Program doesn't handle just movements without initial directions yet
• Any commands must be again given with rover number and initial postitions plus further movements
