요약] K개의 N행 M열 격자가 주어진다.
1번째 상태에서, K개의 박테리아의 위치와 보고 있는 방향이 주어진다.
박테리아가 각 상태마다 아래 방법으로 움직일 때 K개의 박테리아가 전부 (X, Y)에 도달할 때의 상태 번호를 구하여라.
- 박테리아는 자신이 위치한 격자에 쓰여진 수 X를 본다.
- 박테리아가 시계 방향으로 X*90도 회전한다.
- 박테리아가 보고 있는 방향이 격자 밖이면 180도 회전한다.
- 박테리아가 보고 있는 방향으로 한 칸 움직인다.
Luka is bored in chemistry class yet again. This time, he's playing with intelligent bacteria. He has
arranged his K bacteria on a rectangular board divided in N rows, labelled with numbers from 1 to N
starting from the top, and M columns, labelled with numbers from 1 to M starting from the left.
Each bacterium begins its adventure in a certain cell, facing one of the four neighbouring cells, and
carries out the following actions every second:
-
Reads the number X dedicated to that bacterium in the current cell.
-
Turns 90 degrees clockwise, X times.
-
If it is facing a cell outside the board, it turns 180 degrees.
-
Finally, it moves to the cell that it is facing.
Luka has placed a trap in one cell. The trap will activate and kill the bacteria as soon as they all step on
that cell in the same second.
Since Luka only has two hours of chemistry class today, help him determine how long the game will
last, in seconds.
입력
-
The first line of input contains the positive integers N (3 ≤ N ≤ 50), M (3 ≤ M ≤ 50), and K (1 ≤ K ≤ 5).
-
The second line of input contains the positive integers X and Y, the row and column where Luka has
placed the trap.
The remainder of the input consists of bacteria descriptions, for each bacterium i from 1 to K:
-
- two positive integers Xi , Yi - the row and column of the starting cell of bacterium i, and the character Ci
representing the starting direction that the bacterium is facing (U - up, R - right, D - down, L - left).
-
- N by M matrix of digits between 0 and 9, inclusive; the digit in row x and column y represents the
number in cell (x, y) dedicated to bacterium i.
출력
The first and only line of output must contain the total duration of Luka's game, in seconds. If the
game will never end, output -1.
