Haha

Just in case this may help someone:

C++ introduced class template parameter deduction, thus we can omit the repeated type here:

vector c(n, vector<int>(n));

Wow. I wanted to use that Java method

I'm a clojure newbie. So, in clojure it doesn't matter if the type is sequence or vector as long as they can be used the same, right?

Thank you for your explanation. This nested logic chain really blowed my mind up.

The key is to put the coin-loop in the outside, so that we don't get duplicated combinations.

How is it that n need not be used?

Sorry. I overlooked the use itertools::Itertools import.

I can't find the sorted method. What's wrong?

Complexsity too high

How is it that printing things to stdout is also okay on CodeWars? LOL

C++ has the problem of -0, but I don't know if Rust has the same issue.

Yes. The context is throughout the function including the parameters.

If xs.empty() == true, wouldn't the if(xs[0].empty()) be wrong?
