duplicate issue

for java testcase there is extra closing bracket "}"

python new test framework is required. updated in this fork

Error! Illegal number found in row!

Test error feedback is unacceptable. It should at least tell where exactly is wrong.

Sample tests are broken.

I see it too

I started this one with a vague idea, to my surprise it worked in the end

Ruby should be updated to new test framework

The CS version generates n in floating point numbers which is irrelevant to the task !!! This makes a correct solution unable to pass the random tests ~~

Approved some time agoooo

still present

In python initial solution should have 4-space indentation and no final ;.
