Usage

To use the visualizer for testing your solution locally, you'll have to adopt your solution to read the parameters from standard in and write the output to standard out. This doesn't affect the functioning of the solution you submit to our server.

Your program should first read the number of vertices V and the number of elements in edges N, followed by integers representing the elements of edges (in order, each integer in a separate line). After this, you should output the elements of your return from untangle, each integer in a separate line. Remember to flush standard output after writing to it.

To do this, you should implement the following pseudocode:

    V = int(readLine())
    N = int(readLine())
    for (i=0; i<N; i++)
        edges[i] = int(readLine())
    int[] coords = untangle(V,edges)
    for (i=0; i<coords.length(); i++)
        printLine(coords[i])
    flush(stdout)

To run the visualizer with your solution, you should run:

java -jar Visualizer.jar -exec "<command>" -seed <seed>

Here, <command> is the command to execute your program, and <seed> is seed for test case generation. Additionally you can use the following options:

-vis to turn on the visualization (by default it is turned off for testing your solution).
-manual to untangle the graph yourself. The initial layout of the graph vertices is the one used during edges generation. Drag and drop vertices to rearrange them. Click "Ready" when you're satisfied with the result.

Finally, you can print any debug information of your solution to standard error, and it will be forwarded to the standard out of the visualizer.
