首先假设我们不知道 \((X,Y)\)，提取信息看上去很困难。
因此考虑先钦定若干个位置（这里我取了前 \(3 \times 4\) 的矩阵），我们用这些钦定的位置来区分所有的 \((X,Y)\)。对于剩下的位置，可以用来传递信息。
对于一个 \((X,Y)\) ，这些位置会有一些可以染的集合 \(A_{X,Y}\) 和交互库染的集合 \(B_{X,Y}\)。
那么非钦定的位置提供的信息是 \(2^{49-|A_{X,Y}|}\)，我们还需要 \(2^{|A_{X,Y}|-6}\) 的信息去记录 \(S\)。
也就是说，在所有 \(2^{A_{X,Y}}\) 种染色方案中，选择大小为 \(2^{|A_{X,Y}|-6}\) 的子集进行染色。（在染色时可以把钦定的位置染成集合中的样子）。
然后我们要求任意两种染色可能产生的结果是不交的。
事实上 \(43\) 应该是一个非常紧的界，你的解需要做到完美覆盖 \(2^{12}\) 种状态。
取前 \(3 \times 4\) 的矩阵效果会比较好，因为后面的元素可以从 \(2^{12}\) 种状态中随意选择，比较容易找出一组解。
使用一些随机化算法，发现搜出了一组解！然后就通过了。
（我的随机方法：按照 \(A\) 的大小从大到小排序，取对于集合大小不超过 \(10\) 的直接用字典序最小的，大小大于 \(10\) 的随一个顺序。如果有更加厉害的方法请在评论区留言 /kel）
