security cost

Test instructionsThere are n cities, M to the road, from city 1th to transport K cargo to City N.Each has a direction to the road And each road to transport a maximum number of CI goods, the minimum cost.Analysis:Split the edge, each side split into a cost of a, 3a, 5a edge, so that the cost of each side and the flow of the square is proportional to.Since a maximum of K goods are transported, a source point

Hdu1385Minimum Transport Cost (short-circuit variant)Idea: The most short-circuit variant of the output path .. This question lies in multiple groups of inquiries, so I personally think it is more secure to use floyd. In addition, there is a toll in every city, so you can change the Loose Condition in floyd .. What about the output path ?? I use the successor of the output starting point instead of the precursor to the end point .. Because we care abo

Performance issuesLet ' s dig a little deeper. When data is passed to methods as value type parameters, a copy of each parameter are created on the stack. Clearly, if the parameter in question are a large data type, such as a user-defined structure with many elements, or the Me Thod is executed the many times, this could have a impact on performance.In these situations it is preferable to pass a reference to the type, using the ref keyword. This is the C # equivalent of the C + + technique of pa

The internal secrets of large data centers cost as much as 0.145 billion US dollars (1) Most applications and cloud services are inseparable from data centers.

Color a TreeTime limit:1000ms Memory limit:30000kTotal submissions:7144 accepted:2458DescriptionBob is very interested in the data structure of a tree. A tree is a directed graph in which a special node was singled out, called the "root" of the tree, and there is a unique PA Th from the root to all of the other nodes.BOB intends to color all the nodes of a tree with a pen. A Tree has N nodes, these nodes is numbered 1, 2, ..., N. Suppose coloring a node takes 1 unit of time, and after Finishi ng

The details of these implementations are, of course, determined by the compiler, and different compilers have different ways of implementing language features. In most cases, you don't have to worry about these things. However, the implementation of some features has a great impact on t

Topic:The table has n legs, and when the table is unbalanced, it can be cut off to achieve maximum balance. The so-called maximum balance state refers to-the longest leg of the table is more than half the number of legs of the table. But the cost of cutting the legs of the table is different, and the cost of achieving the maximum balance is minimal.Input:62 2 1 1 3 34 3 5 5 2 1Output:8The following is the l
