Topic: Given the source binary tree, the design algorithm realizes its mirror image. Ideas: For the problem of binary tree, it is necessary to consider the non recursive implementation of the recursive method. This is a good recursive

AOE network : In a representation of the project with the right to the graph, using vertices to represent events, with a direction to represent the activity, the edge of the weight of the duration of the activity, called such a map called the edge

G={v,e} is a direction graph with n vertices, the vertex sequence in V is V1,v2,......, vn, if there is a path from Vertex VI to VJ, vertex VI must precede vertex VJ in vertex sequence. It is said that such a vertex sequence is a topological

Vector is a very useful container in C + +, and here's a summary of the vector based on several articles. 1. The document contains First, add #include at the beginning of the program to include the required class file vector, plus a using namespace

Tuple is the return of multiple parameters, C # 4.0 introduces Supports up to 8 parameters, and the eighth parameter is tuple, meaning that more than 8 arguments begin nesting Calls A function returns multiple types so that no output input

The definition of the queue template class is in the header file. The queue is very similar to the stack template, and the queue template also needs to define two template parameters, one is the element type, one is the container type, the element
