Some import and export functions are often encountered during the project process. Today, I may leave it empty.
(If there is something wrong, please correct it. If you solve the problem, you can easily record it for your reference)
First, the basic project process diagram is as follows:

The same waterfall flow effect but there are many ways to achieve, using recursion, bubbling and so on can achieve the purpose you want. This is to say that the use of similar recursive return to achieve this effect of the original scheme. This program personally believes that the difficulty coefficient is low1PHP2 //no data source, using
A classic algorithm is used to find the largest stream, that is, BFs is used to find the augmented path every time, to ensure that the augmented path is found to have the least number of arcs, that is, the so-called Edmonds-Karp Algorithm. It can be proved that the maximum short-circuit augmented time is not more than V * E, and the BFS time is O (e) each time ), therefore, the time complexity of Edmonds-Karp is O (V * E ^ 2 ).
