The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

按照Clifford A . Shaffer《数据结构与算法分析(第二版)》指导,用C#实现的B+树,接口定义良好。最好重写“从文件载入新建树部分”的代码以提高建树效率。实现细节之一:当“需要插入子节点的节点”已满而相邻节点未满时会平分两者节点而不是分裂该节点。
