三消算法首要实现的就是找到所有三个或三个以上的同样颜色，所以我们思路是：判断每个点进行上下左右四个方向移动后，能得到三个及以上的相连。
经过分析，当我们向一个方向移动时，会有四种情况符合条件，所以当一个点符合消除时，需要判断周围点的情况共有16种！
例如：当红色圈向右移动一格能消除时，他周围的情况必然时图下四种状态：
1.与右边两个绿圈消除
2.与右上方两个蓝圈消除
3.与右下方两个黄圈消除
4.与右边上下各一个绿色正方形消除。
所以，我们的要做的是：
第一步：将图片转换成矩阵：
list_ = [["绿", "红", "红", "紫", "绿", "紫", "蓝"],
["紫", "紫", "绿", "黄", "绿", "蓝", "紫"],
["紫", "红", "紫", "红", "紫", "蓝", "黄"],
["蓝", "紫", "紫", "蓝", "黄", "紫", "绿"],
["红", "蓝", "绿", "紫", "黄", "蓝", "绿"]]
第二步：
从上往下，从左往右，遍历每一个点，并且遍历它周围的特定位置，判断是否移动该点，能和周围的点结合实现消除。
用于算法计算的坐标轴：
第三步：代码实现：
list_ = [["绿", "红", "红", "紫", "绿", "紫", "蓝"],
["紫", "紫", "绿", "黄", "绿", "蓝", "紫"],
["紫", "红", "紫", "红", "紫", "蓝", "黄"],
["蓝", "紫", "紫", "蓝", "黄", "紫", "绿"],
["红", "蓝", "绿", "紫", "黄", "蓝", "绿"]]
