Description

In a modernized warehouse, robots are used to fetch the goods. Careful planning is needed to ensure that the robots reach their destinations without crashing into each other. Of course, all warehouses are rectangular, and all robots occupy a circular floor space with a diameter of 1 meter. Assume there are N robots, numbered from 1 through N. You will get to know the position and orientation of each robot, and all the instructions, which are carefully (and mindlessly) followed by the robots. Instructions are processed in the order they come. No two robots move simultaneously; a robot always completes its move before the next one starts moving.
A robot crashes with a wall if it attempts to move outside the area of the warehouse, and two robots crash with each other if they ever try to occupy the same spot.

Input

The first line of input is K, the number of test cases. Each test case starts with one line consisting of two integers, 1 <= A, B <= 100, giving the size of the warehouse in meters. A is the length in the EW-direction, and B in the NS-direction.
The second line contains two integers, 1 <= N, M <= 100, denoting the numbers of robots and instructions respectively.
Then follow N lines with two integers, 1 <= Xi <= A, 1 <= Yi <= B and one letter (N, S, E or W), giving the starting position and direction of each robot, in order from 1 through N. No two robots start at the same position.

Figure 1: The starting positions of the robots in the sample warehouse
Finally there are M lines, giving the instructions in sequential order.
An instruction has the following format:
< robot #> < action> < repeat>
Where is one of

• L: turn left 90 degrees,
  
• R: turn right 90 degrees, or
  
• F: move forward one meter,

and 1 <= < repeat> <= 100 is the number of times the robot should perform this single move.

Output

Output one line for each test case:

• Robot i crashes into the wall, if robot i crashes into a wall. (A robot crashes into a wall if Xi = 0, Xi = A + 1, Yi = 0 or Yi = B + 1.)
  
• Robot i crashes into robot j, if robots i and j crash, and i is the moving robot.
  
• OK, if no crashing occurs.

Only the first crash is to be reported.

题意：

给出几个机器人，对其进行三种操作，判断是否撞墙、互撞或者什么都不发生。

感想：

1、建坐标很容易搞错。我以前习惯x代表行也就是N----S方向，y代表列即东西方向。然后这题恰好是用x表示东西，然后y表示南北。对应的dx[ ]和dy[ ]数组也要

      变。

2、转动的那个，左转和右转开了两个数组。方向变换的时候，开始是一次一次的转，用for循环。先找到操作前的初始方向用tmp记录。然后每次用+1mod 4找

       转动一次后的方向，tmp又忘了更新。后来想想完全没必要，直接+转动次数mod 4就行了。

3、原来提交时不把重定向去掉会RUNTIME ERROR 啊。

4、我又把变量混用了。明明t 已经做了记录CASE数的变量，后来又把它用来作记录操作时机器人编号的变量，导致CASE值被擦掉了。出现了输出组数有问题的

        情况。

5、思路一直都是对的，比较欣慰。但是各种小的犯二啊。。
