Tsinsen public problems

The problems' sorce: Tsinsen

Note:

Because of Tsinsen won't supply the online judge service for users from 2019-09-01 on and in fact the website has stopped the service now (2019-04-08), I can not submit my code on the website. The problems in the list above which marked 'TODO' means the solution code is from other websites.

There are many good solutions from below websites:
