DWITE Online Computer Programming Contest, October 2009, Problem 1

Having decided to capitalize on your awesome programming skills, you've set out to create and sell a mobile application at ~\$0.99~ per copy. Since the application is hosted and distributed through a managed platform, the store gets to keep ~30\%~ from each sale.

Given that you have an idea of how much profit you want to make off your hard work, at least how many ~1\,000~s of copies must be sold? (That is, the answer is rounded to the next ~1\,000~).

The input will contain 5 lines, integers ~0 \le N \le 1\,000\,000~, the minimum profit you want to keep.

The output will contain 5 lines, integer value of the number of copies needed to be sold, rounded to the next ~1\,000~.

For example: if you want to make ~\$1\,000~, then ~(1\,444 \text{ copies} \times $0.99) - 30\% = \$1\,000.692~. (~1\,443~ copies will earn below ~\$1\,000~). ~1\,444~ rounded to the next ~1\,000~ is ~2\,000~; thus the answer is ~2\,000~.
