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 the method permute, 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: return the permutation S-1, S-2, ..., 1, 0.
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:
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.
-vis : Turns on visualization. By default only permuted matrix (or original if no executable is given) is shown. White cells represent zero elements, blue and grey - positive and negative elements which are not part of the largest connected region, green and red - positive and negative elements which are part of the largest connected region. Darker colors represent elements with greater absolute values.
-debug : Outputs visualizer debug information.
-size <SZ> : Sets size of a square which represents one element of the matrix.
-show-original : If set, shows original matrix in addition to the permuted one (original matrix on the left pane and permuted matrix on the right pane).
-save : If set, saves the image to file <seed>.png.
