Original address This is my personal AC first topological sorting problem.The title explains the outcome of several sets of matches. Infer the final ranking. According to test instructions this is an obvious topological ordering problem.Attention Assuming there are multiple situations due to possible rankings, make sure that the numbers are small before. The data entered by the topic may have repeated edges Topology sequencing first
assigned to the DP array, the topology is sorted, and finally the point of 0 is traversed, and the maximum value is obtained.AC Code:#include "iostream" #include "Cstdio" #include "CString" #include "algorithm" #include "queue" #include "stack" #include " Cmath "#include" utility "#include" map "#include" set "#include" vector "#include" list "#include" string "using namespace Std;typedef Long Long ll;const int MOD = 1e9 + 7;const int INF = 0x3f3f3f3
each test data, the first line has two integers n (1 Then m lines, two integers a and b per line, indicate that a constraint a must precede the B number.A and B are necessarily different.Output the order in which each test data is queued, separated by a space. Sample INPUT15 103 The 2 sample OUTPUT1 2 3 4 5 The main topic: in a given order, find a set of numbers the lower the priority of the scheme, as far as possible to arrange 1 in front, if there are many cases Then as far as possible arrang
HDU-4857Test instructions is to do a qualifying sort, using the topological sequence.I started with a lot of WA, only to find that there are a few examples too, found 1->2->3 ... the order is not guaranteed.Later I wanted to use and check the strong company, or WA;Later found that the use of reverse topology sorting + priority queue to pass;Notice here that the entry to the 0 is changed into a 0-degree queueHere is the AC code:#include #include#includ

Positive words because these two conditions are not good maintenance, so think of using reverse topol

Unfortunately, the tasks independent and the execution of one task is only possible if and tasks with already be En executed.InputThe input would consist of several instances of the problem.

Trim curve Brushes: This brush works like a clipping brush, but the strokes on the geometry are reversed, ZBrush removes all parts of the geometry from the trim curve and closes the resulting hole. Bridging brushes: Create polygons in bridging between surface holes, polygon group boundaries and even produce folding edges-all operations need to be clicked 2 times. You can manipulate the brush with a closed or open curve. Line brushes: Using this brush, you will no longer need to rely on a
less, even if one is missing, it also shows that the network has a loop, not a AOV network. The basic idea of topology sequencing for AOV Networks is: Select a vertex output of 0 from the AOV network, then delete the vertex and remove the arc at the end of the vertex, and continue to repeat this step until all vertices are output or 0 vertices are not present in the AOV network. Because in the process of topolo
When trying to introduce asynchronous Javascript™and XML (AJAX) programming technology into a network environment, there are often some difficulties encountered. Brief introduction An exciting feature of Ajax architecture is the ability to aggregate content from multiple data sources and create an entirely new site or WEB application. For example, you can create a WEB application that combines information from a variety of meteorological services to provide weather information for several ski

When you see the following support topology it is only beginning to doubt the relationship between the Falconstor CDP and the database.
