This is my code suite, including homemade build and run tools and testing library, for practicing theGrokking the Coding Interview algo patterns in Java.

Add methods to an existing .java file and tests in the class'smain() method (using the Tester class for test utilities - see example main() methods in existing files)

To create a new .java file/class, rungtool new [classname], e.g.gtool new GrokkingTopSort, which will create the corresponding .java file (e.g. GrokkingTopSort.java) with initial boilerplate code at the top level.

• The command line toolgtool can handle allclean,build, andrun operations, using these as the respective command argument (e.g.gtool clean).
• Run the tool without an argument to see the available commands. Run with commands to perform the desired operations.

• gtool build will automaticallyclean before building.
• gtool run will neither build nor clean automatically. To get all of these in one, use thegtool br command (see below)

Thebr command argument will clean, build, and run the given class all in one (you don't need to include the package name for the class).

Example:gtool br GrokkingFastSlowPointers will clean and build all .java files and then run the main method for theGrokkingFastSlowPointers class.

Feed a class name to this method (e.g.gtool new GrokkingTopSort) to conveniently create a respective .java class file (e.g.GrokkingTopSort.java) with the appropriate package name (set withDEFAULT_PACKAGE_NAME) and boilerplate class code already added.

If for some reason you want a verbose printout of the stages being performed bygtool, simply change theinitializedVERBOSE value to1. Maybe I'll add a-v flag but I don't feel like it right now.
