web Front End Case-Developing 3D Dragging Photo Wall

This code is 136 lines, written in css3 and javascript. Now the albums on the network are mostly tiled. If there are many photos, they look very tired. Of course, this is my personal point of view, so this time I made a 3D album dragging effect, which looks beautiful and not tired to watch. Knowledge points: CSS33D effect, CSS3 excessi ...

LOJ6002 [Network Flow Question 24-3] Drop Small Path Coverage Bipartite Drop Large Matching

Everyone is strong enough to share their support. Topic: _Given a directed graph G=(V,E).Set P to be a set of G's simple paths with disjoint vertices.If each vertex in V happens to be on a path of P, P is said to be a path coverage of G.A path in P can start from any vertex of V and have an arbitrary length, especially 0.The minimum path cov ...

An algorithm for searching all paths between two points based on a graph's contiguity list implementation

The algorithm is implemented in C++. Why write this algorithm? Because it is so hard to find only the implementation of the adjacency matrix on the network, I have made an implementation of the adjacency chain table myself, which can increase the speed. This is achieved by using one of three stacks to traverse all vertices, the second stack t ...
