POJ 3480 Crashing Robots

[★★☆☆☆]模拟

• 题目大意：

  输入仓库大小，和机器人的位置，朝向。根据指令进行操作，如果两个机器人相撞或者机器人撞墙则输出，结束。

• 样例

  输入：
  4
  5 4
  2 2
  1 1 E
  5 4 W
  1 F 7
  2 F 7
  5 4
  2 4
  1 1 E
  5 4 W
  1 F 3
  2 F 1
  1 L 1
  1 F 3
  5 4
  2 2
  1 1 E
  5 4 W
  1 L 96
  1 F 2
  5 4
  2 3
  1 1 E
  5 4 W
  1 F 4
  1 L 1
  1 F 20

  输出：
  Robot 1 crashes into the wall
  Robot 1 crashes into robot 2
  OK
  Robot 1 crashes into robot 2

• 解题思路：

  模拟水题。。没有算法，细心就行。
