在这个问题上的二叉树指定了对序列（N，S），其中n是在节点的路径，从根本上是由字符串s的值路径是一个序列的L和R的其中L表示左支和R表示右支。在树上面的图解，含13节点（13，RL＃指定，并含2节点LLR＃2，＃指定。根节点指定＃5）空字符串表示的路径从根到自身。二进制树被认为是完全指定，如果每根树中的所有节点的路径上的节点都被赋予一个值一次。

In this problem a binary tree is specified by a sequence of pairs (n,s) where n is the value at the node whose path from the root is given by the string s. A path is given be a sequence of L's and R's where L indicates a left branch and R indicates a right branch. In the tree diagrammed above, the n
