Nice problems. Thank you for the round! Hope there will be more such rounds. Please keep giving T-shirts to 50(or more!) random participants who solve atleast one problem. This will bring more participation for sure because it's too hard for people like me to get in top 50. :(

Edit: Nvm, I guess there is nothing wrong with the solution. But there is a bug in displaying dollar sign in comment and post.

Hi, I'm new to Kotlin. Correct me if I'm wrong, but I think the print part in the solution for problem D is incorrect. I guess Kotlin no longer use $$$$$ for template expression.

It should be:

~~~~~ println(a.joinToString("\n") { "$$${it.size} ${it.joinToString(" ")}" }) ~~~~~
