我有一个程序可以扫描图像并将宝石转换成特定的数字。请看下图：
所以我有一张有数字的桌子。数字1代表黄色宝石，2代表蓝色等…
比如：
A B C D E
1 | 1 2 3 4 5
2 | 3 5 2 4 1
3 | 1 4 4 1 2
4 | 3 3 2 1 5
5 | 5 1 5 2 5
我想计算一步，得到3个相等的数字（宝石）水平或垂直例如，在这个表中，如果我将E2与D2交换，D2将为1，而D2、D3、D4将创建一个有效步骤，因为它都是1。我正在使用VB.NET 2010。
我的桌子是8x8号的，这只是上面的一个例子。
现在我只有多个变量的值（a1=1，a2=3，依此类推）。
我希望你能理解我的问题，任何帮助都将不胜感激。

这个程序可以使用任何大小的电路板。这个程序基于我在游戏中搜索匹配项的方式（我认为这是蛮力）。
编辑
解算器似乎无法在第一个gem上找到匹配项（参见下面的示例）。
五，二，五
2，5，3号
1，5，4
如果将算法应用于上述示例，则找不到匹配项。
我已经修好了。现在有一个
IsMatchOnFirst()方法来处理这些情况。有关更改，请参见更新的代码。
