Imagine you are in charge of software development on the Mars exploration team. Now you have to write a control program for the exploration vehicle landing on Mars, and control the actions of the rover according to the control instructions sent by the earth.

The instructions received by the rover fall into three categories:

1. Initialization information: The landing location (x, y) and heading (N, S, E, W) information of the rover;
2. Move instructions: The rover can move forward (M), one space at a time;
3. Turn instructions: The rover can turn left 90 degrees (L) or right 90 degrees (R).

Due to the long distance between the Earth and Mars, the instructions must be sent in batches. After the rover executes the complete batch of instructions, it will report its location coordinates and heading.
