Helpful information
In order to use the offline tester / visualizer tool for testing your solution locally, you'll have to modify your solution
by adding the main method that interacts with the tester / visualizer via reading data from standard input and
writing data to standard output. As long as you do not change the implementation of methods buildJunctions and buildRoads, this
doesn't affect the way your solution works when submitted to our server.
Here are example solutions for different languages, modified to be executed with visualizer. They all implement the same approach: build a single junction at point (0, 0) and connect each city to it with a road.
To run the tester with your solution, you should run:
java -jar Tester.jar -exec "<command>" -seed <seed>
Here, <command> is the command to execute your program,
and <seed> is seed for test case generation.
If your compiled solution is an executable file, the command
will be the full path to it, for example, "C:\TopCoder\solution.exe" or
"~/topcoder/solution". In case your compiled solution is to be run
with the help of an interpreter, for example, if you program in Java,
the command will be something like "java -cp C:\TopCoder Solution".
Additionally you can use the following options:
-
-novis : Turns off visualization. By default tester creates a file <seed>.png with the map of cities, junctions and roads built. Cities are marked with black dots, and junctions are marked with green/red dots depending on whether the construction succeeded or not.
-
-debug : Print debug information during test run.
Finally, you can print any debug information of your solution to standard error,
and it will be forwarded to the standard out of the tester.
