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?

Just start to learn rust.

Complexsity too high

aye. If you already have a boolean, then just use the boolean. The conditional is redudant.

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