Description
html markup
shown to student

This program should take an integer <tt>n</tt> as input,
then print out the square roots of the numbers from <tt>0</tt> to <tt>n-1</tt>.
<p>
The input/output is provided for you. Fill in the loop so that the array
<tt>values</tt> contains the desired square roots.
<p>
Remember that <tt>sqrt(x)</tt> is the function to compute the square root of
<tt>x</tt>.

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": "5"},
{"stdin": "20"},
{"stdin": "0"}
]

Forbidden substrings
json list of strings
e.g. ["for","while"]

remove
Solution visibility remove
Java imports
json list of importables
e.g. ["java.util.*"]

remove
Override Java classname
else defaults to
websheet name
remove
Dependent on other websheets?
json list of websheet names in this folder
e.g. ["DataStructure"]

remove
Is example?
i.e., just a demo
remove
Add compiler flag(s)
json list of flags
e.g. ["-Wno-unused-variable"]

remove
Remove default compiler flag(s)
json list of flags
see default_cppflags
e.g. ["-Wno-write-strings"]
