问满足a^3 + b^3 + c^3 + n = (a+b+c)^3 的 (a,b,c)的个数 可化简为 n = 3*(a + b) (a + c) (b + c) 于是 n / 3 = (a + b)(a + c) (b + c) 令x = a + b,y = a + c,z = b + c,s = n / 3 s = xyz 并且令x <= y <= z,于是我们解s = xyz这个方程,可以枚举x,y得到z. 得到(x,y,z)后便可以得到a,b,c但可能有不符合条件的三元组,化简系数矩…

E. Connected Components? You are given an undirected graph consisting of n vertices and edges. Instead of giving you the edges that exist in the graph, we give you m unordered pairs (x, y) such that there is no edge between x and y, and if some pair…

Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. Example 1: 0          3 |          | 1 --- 2    4 Given n = 5 and…

Write a program to find the strongly connected components in a digraph. Format of functions: void StronglyConnectedComponents( Graph G, void (*visit)(Vertex V) ); where Graph is defined as the following: typedef struct VNode *PtrToVNode; struct VNode…

We will learn how to use withRouter() to inject params provided by React Router into connected components deep in the tree without passing them down all the way down as props. The app component itself does not really use filter. It just passes the fi…
