1014 collision Robot

Description

Some robots are walking in the house. They need to complete the commands without colliding with each other. The map is rectangular, and each Robot occupies a grid, we know the initial location and direction of the machine operator, as well as a series of commands. commands are ordered, and no two commands occur simultaneously. For example:

Input

Multiple groups of data, number of the first row of Data K

Each group of data starts with two integers n, m, indicating the size of the map, n is the size of the W-E direction, M is the size of the N-S direction (n, m <= 100)

The next line contains two integers: p, q (p, q <= 100), indicating P robots and Q commands.

Next, P lines describe the initial information, location (x, y) of the robot)

(1 <= x <= N, 1 <= Y <= m), and a letter indicates the direction ('n', 's', 'E ', 'W ')

Next, the Q-line describes the instruction. The instruction structure is as follows:

<Robot I> <action> <repeat>

Indicates the robot, Action type, and number of repetitions.

There are three types of actions

1. 'L': 90 degrees left
2. 'R': Right turn 90 degrees
3. 'F': Forward a grid

Repeat times will not exceed 100.

In the event of a collision, the robot stops running and outputs relevant error information.

Output

There are 3 types:

If the I-th robot (x = 0 or Y = 0 or X = n + 1 or Y = m + 1), output the robot I crashes into the wall

If I collide with J, I is the mobile robot that outputs robot I crashes into robot J

If no collision occurs, output OK

Sample input 2
5 4
2 2
1 1 E
5 4 W
1 F 7
2 F 7
5 4
2 2
1 1 E
5 4 W
1 L 96
1 F 2 sample output

Robot 1 crashes into the wall
OK

Solution:
This is a simulated question. You only need to follow the meaning of the question.
I used two arrays of structures, one for storing the location and orientation of the robot, and the other for marking the map size and whether there are other robots in each grid of the map.
When a robot moves, it first determines whether it is out of bounds and then whether it hits another robot. Follow the input sample of the program.
