After finding the maximum stream, you can increase the maximum flow by asking which sides increase the capacity.Train of Thought: for a path that can be increased, it must have been full stream, and from the source point to the sink point, there is still a residual capacity, in this

by key. For example: Sort by the length of the element, you can make the Key=len.>>> a=['de','s','HHT','Joiu']>>> A.sort (key=len)>>>a['s','de','HHT','Joiu']Another parameter, reverse, is a simple Boolean value (Ture or false) to indicate whether to reverse-order>>> a=[2,4,9,1,7,3,6,5]>>> a.sort (reverse=True)>>> a[9, 7, 6, 5, 4, 3, 2, 1](2) Reverse functionThis function can store the elements of the list

At that time to learn this algorithm is only a rough understanding of the fact that a lot of details are not understood at all. Make up the stem by bzoj_1007.FirstFirst, we'll divide the process of the algorithm into four stages according to the inclination of the straight line.The first stage is (-PI,-PI/2) This stage after the focus must be from the right to the left (the first point to add the most right, the last point of the most left, the top of the stack of elements on the left)The second

I. Overview of SPRINGIOC containers IOC container and dependency reversal mode In object-oriented systems, objects encapsulate data and process data, and the dependencies of objects are often reflected in the dependence on data and methods. These dependencies can be done by giving the object's dependency injection to the framework IOC container. He can decouple the code and improve the testability of the code.The implementation of dependency control i
