Optimal Programs As you know, writing programs is often far from being easy. Things become even harder if your programs have to be as fast as possible. And sometimes there is reason for them to be. Many large programs such as operating systems or dat…

A group of friends went on holiday and sometimes lent each other money. For example, Alice paid for Bill's lunch for $10. Then later Chris gave Alice $5 for a taxi ride. We can model each transaction as a tuple (x, y, z) which means person x gave per…

We all know that the shortest path problem has optimal substructure. The reasoning is like below: Supppose we have a path p from node u to v, another node t lies on path p: u->t->v ("->" means a path). We claim that u->t is also a sh…

由结构体组成的表与结构体中的表. 在用追溯形式建立家家谱树时,我们通常从某个后代除法,依次处理它的父母,组父母等.而构建树时,我们会不断添加谁是谁的孩子,而不是写出谁是谁的父母,从而建立一颗后代家谱树. 绘制后代数与绘制祖先树一样,只是将所有箭头的方向都反了过来: (define-struct parent (children name date eyes))children数量不固定,怎么办?自然的选择是另children代表由parent结构体组成的表,这个表代表孩子,parent是结构体:…

OPTM - Optimal Marks You are given an undirected graph G(V, E). Each vertex has a mark which is an integer from the range [0..231 – 1]. Different vertexes may have the same mark. For an edge (u, v), we define Cost(u, v) = mark[u] xor mark[v]. Now we…
