After finishing university, Anton decided to start looking for a job.
He immediately went to the website. When he went to the "Vacancies" tab, he saw a lot of job openings. However, the exact number of vacancies was not specified on the website. He knows that there are a maximum of vacancies on each page, and the vacancies take up pages.
You have a good understanding of how the website works. When a new vacancy is added, it is added to the last page. If there are already vacancies on the last page before adding a new one, a new page is created and the vacancy is added there.
Knowing this information, determine the minimum and maximum number of vacancies.
输入格式
The first line of the input contains a single integer () --- the number of pages with vacancies.
输出格式
Print two integers --- the minimum and maximum number of vacancies that could be on the website.
