Web零、先修课程. 首先，在开始理解DP的思想前，你需要. 1. 完成HDU里面的递推求解专题练习（For Beginner）那7道题（这些题很简单，题解请在博客中搜索），这对你理解DP有很大的帮助。. 2. 对递归搜索（比如深度优先搜索，DFS）有一定了解。 Webdetail by Hurwitz [12] in 1894 and the sequence of (distinct) Farey pairs is called the Hurwitz chain for by Philippon in [23]. We can encode the Hurwitz chain of an irrational 2(0;1) by a unique in nite word in the letters Rand L. We label a pair with Rif within the pair the old fraction is to the right of the new one and Lif it is to the left.
