Template / Reference solution

#include <algorithm>
#include <iostream>
using namespace std;

long maxprod(int n) {
if (\[n <= 3]\)
return \[n]\;
else
return \[max(2*maxprod(n-2), 3*maxprod(n-3))]\;
}

int main(int argc, char* argv[]) {
cout << maxprod(atoi(argv[1])) << endl;
}

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 [{}]

[
{"args": ["6"]},
{"args": ["7"]},
{"args": ["8"]},
{"args": ["20"]},
{"args": ["60"]}
]

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"]
