shown to student

Write a program to compute the Annual Percentage Yield which is given by:

$$\Large APY = ({ 1 + \frac{r}{n}})^n - 1$$

where r is the interest rate expressed as a decimal (e.g. 3% should be entered as <code>0.03</code>) and n is the number of times compounded.

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 3", "args":[]},
{"stdin":"1 100", "args":[]},
{"stdin":"3 16", "args":[]},
{"stdin":"-7 5", "args":[]}

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

remove
Override Java classname
else defaults to
websheet name

Dependent on other websheets?

Is example?
i.e., just a demo
