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 placeKnights, 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: place a knight in each cell independently with a probability 0.5.
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:
-
-vis : Turns on visualization. Placed knights are shown as black circles or a shape of a chess knight, depending on the cell size. The numbers in the cells are the required numbers of knights attacking that cell (the elements of board). Cell color indicates the number of actual knights attacking the cell: white means exact match with the required number, red means too many attacks, and blue means too few.
-
-size <SZ> : Sets size of a square which represents one cell of the board.
-
-debug : Outputs visualizer debug information.
-
-save : If set, saves the image to file <seed>.png.
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.
