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 thousands of copies must be sold? *(That is, the answer is rounded to the next 1000.)*

The input file **DATA1.txt** will contain 5 lines, integers 0 ≤ `N` ≤ 1,000,000; the minimum profit you want to keep.

The output file **OUT1.txt** will contain 5 lines, integer value of number of copies needed to be sold, rounded to the next 1000.

*For example:* If you want to make $1000, then (1444 copies × $0.99) − 30% = $1000.692. (1443 copies will earn below $1000). 1444 rounded to the next 1000 is 2000; thus the answer is 2000.
