• Executable JAR of the visualizer
• Source code of the visualizer

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 method playIt, this doesn't affect the way your solution works when being submitted to our server.

To simulate a single test case, your program should implement the following protocol (each integer / string is to be read from / printed in a separate line):

• Read integer colors.
• Read integer N.
• Read N strings board[0], board[1], ..., board[N-1].
• Read integer startSeed.
• Call playIt(colors, board, startSeed). Let ret be the return value.
• Print integers ret[0], ret[1], ..., ret[29999]. Flush standard output stream.

In other words, you should implement the following pseudocode in the main method of your solution:

    colors = parseInt(readLine())

    N = parseInt(readLine())
    for (i=0; i < N; i++)
        board[i] = readLine()

    startSeed = parseInt(readLine())
   
    ret = playIt(colors, board, startSeed)

    for (i=0; i < 30000; i++)
        printLine(ret[i])

    flush(stdout)

In order to run the tester / visualizer, you should use the following command:

java -jar SquareRemoverVis.jar -exec "<command>"

<command> is the command you would use to execute your solution. If your compiled solution is an executable file, the command will just 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 parameters (all are optional):

• -seed <seed>. Sets the seed used for test case generation. Default value is 1.
• -novis. Switches the visualization off, leaving only text output.
• -sz <cell size>. Sets the size of one cell of the board, in pixels. The default value is 30.
• -delay <delay>. Sets the delay (in milliseconds) between visualizing consecutive frames. The default value is 100.
• -pause. Starts visualizer in paused mode. See more information below.
• -quit <quit time>. If this option is used, visualizer will wait for quit time milliseconds after showing the entire gameplay sequence and then it will automatically quit. (The default behaviour when this option is not used would be to wait for you to close the visualizer window.)

Visualizer works in two modes. In regular mode, frames are visualized one after another with a delay specified with -delay parameter. In paused mode, the next frame will be visualized only when you press any key (except space). The space key can be used to switch between regular and paused modes. The default starting mode is regular. You can use -pause parameter to start in paused mode.

You can print any debug information of your solution to the standard error stream and it will be forwarded to the standard output of the tester.
