Hackerrank profile: tsibin_andrey
Not each solution from hackerrank presented in this repository due to technical problems with my notebook occured in the process of passing tasks.
Some of the tests have no asserts but just System.out::println for visual checking of the solution output. It was made in order to save time on writing tests with complex assertions.
