Description

The game named “Same” is a single person game played on a 10 \Theta 15 board. Each square contains a ball colored red (R), green (G), or blue (B). Two balls belong to the same cluster if they have the same color, and one can be reached from another by following balls of the same color in the four directions up, down, left, and right. At each step of the game, the player chooses a ball whose cluster has at least two balls and removes all balls in the cluster from the board. Then, the board is “compressed” in two steps:

1. Shift the remaining balls in each column down to fill the empty spaces. The order of the balls in each column is preserved.

2. If a column becomes empty, shift the remaining columns to the left as far as possible. The order of the columns is preserved.

For example, choosing the ball at the bottom left corner in the sub-board below causes:

The objective of the game is to remove every ball from the board, and the game is over when every ball is removed or when every cluster has only one ball. The scoring of each game is as follows. The player starts with a score of 0. When a cluster of m balls is removed, the player’s score increases by (m-2)^2 . A bonus of 1000 is given if every ball is removed at the end of the game.

You suspect that a good strategy might be to choose the ball that gives the largest possible cluster at each step, and you want to test this strategy by writing a program to simulate games played using this strategy. If there are two or more balls to choose from, the program should choose the leftmost ball giving the largest cluster. If there is still a tie, it should choose the bottommost ball of these leftmost balls.

Input

You will be given a number of games in the input. The first line of input contains a positive integer giving the number of games to follow. The initial arrangement of the balls of each game is given one row at a time, from top to bottom. Each row contains 15 characters, each of which is one of “R”, “G”, or “B”, specifying the colors of the balls in the row from left to right. A blank line precedes each game.

Output

For each game, print the game number, followed by a new line, followed by information about each move, followed by the final score. Each move should be printed in the format:

Move x at (r,c): removed b balls of color C, got s points.

where x is the move number, r and c are the row number and column number of the chosen ball, respectively. The rows are numbered from 1 to 10 from the bottom, and columns are numbered from 1 to 15 from the left. b is the number of balls in the cluster removed. C is one of “R”, “G”, or “B”, indicating the color of the balls removed. s is the score for this move. The score does not include the 1000 point bonus if all the balls are removed after the move.

The final score should be reported as follows:

Final score: s, with b balls remaining.

Insert a blank line between the output of each game. Use the plural forms “balls” and “points” even if the corresponding value is 1.

题意:在一个固定大小为10x15的矩形区域A内被RGB三种颜色的小球填满。

现在按如下步骤操作:

1. 删除区域A内最大的一片区域M(任意颜色都可以,只要其占有区域最大)

2. 删除M后,自然会出现空的位置,在M区域上方的小球自然下落;

当删除M后出现空列时,右边的列往左填充。

注意是以“列”为单位填充,非空列只能整列往空列移动。

移动后,各个小球之间的相对顺序 与 移动前一样。

3. 当区域A剩余小球数为0,或A内的最大区域为1时,游戏结束。否则返回1。

输出每一步的得分,最后输出总得分。**

简单的模拟,没有什么坑点
