本文探讨了Piotr在蚂蚁行走模拟中的实验，详细解释了蚂蚁如何在水平杆上移动，包括它们如何改变方向以及在碰撞时的行为。通过设置特定参数如蚂蚁数量、移动时间及初始位置和方向，作者展示了蚂蚁群体的动态行为，特别是它们如何在碰撞后重新调整方向，最终呈现出一种看似无序但有序的群体运动模式。
Time Limit: 2 seconds
| "One thing is for certain: there is no stopping them; the ants will soon be here. And I, for one, welcome our new insect overlords." |
Piotr likes playing with ants. He has n of them on a horizontal pole L cm long. Each ant is facing either left or right and walks at a constant speed of 1 cm/s. When two ants bump into each other, they both turn around (instantaneously) and start walking in opposite directions. Piotr knows where each of the ants starts and which direction it is facing and wants to calculate where the ants will end up T seconds from now.
Input
The first line of input gives the number of cases, N. N test cases follow. Each one starts with a line containing 3 integers: L , T and n (0 <= n <=
10000). The next n lines give the locations of the n ants (measured in cm from the left end of the pole) and the direction they are facing (L or R).
Output
For each test case, output one line containing "Case #x:" followed by n lines describing the locations and directions of the n ants in the same format and order as in the input. If two or more ants are at the
same location, print "Turning" instead of "L" or "R" for their direction. If an ant falls off the pole before Tseconds, print "Fell off" for that ant. Print an empty line after each test case.
| Sample Input | Sample Output |
2 10 1 4 1 R 5 R 3 L 10 R 10 2 3 4 R 5 L 8 R |
Case #1: 2 Turning 6 R 2 Turning Fell off Case #2: 3 L 6 R 10 R |
对于这一些运动的蚂蚁，当他们因碰撞而掉头时，看上去和两只蚂蚁对穿而过没有任何区别；
