零. 优先级 在C++ Primer一书中,对于运算符的优先级是这样描述的: Precedence specifies how the operands are grouped. It says nothing about the order in which the operands are evaluated. 意识是说优先级规定操作数的结合方式,但并未说明操作数的计算顺序.举个例子: 6+3*4+2 如果直接按照从左到右的计算次序得到的结果是:38,但

Description Given a connected undirected graph, tell if its minimum spanning tree is unique. Definition (Spanning Tree): Consider a connected, undirected graph G = (V, E). A spanning tree of G is a subgraph of G, say T = (V', E'), with the following
