Java test suite
See manual

C++ test suite
json list of stdin/args tests
e.g. [{"stdin":"hi", "args":["4", "5"]}, {"stdin":"noargs"}]
to just run once with no input use [{}]

[{"stdin":"90018 90018 90007 90018 90089 90007 90006"}]

Solution visibility remove
Java imports
json list of importables

remove
Override Java classname
else defaults to

remove
Dependent on other websheets?
json list of websheet names in this folder
e.g. ["DataStructure"]

Is example?
i.e., just a demo
