You are sitting at your computer surfing the internet when a chance forum post stirs memories of an idyllic past. There were so many different ways of representing rational numbers back then - percentages, decimals, and of course the mixed fraction. There was always something so wonderful about mixed fractions - the way they quickly told you how big the number was yet still conveyed the subtleties of the fractional part. Such elegance... You shed a silent tear for days long gone.

In this task you are given a fraction in the form *n*/*d*, where 1 <= *d* < *n* <= 1,000,000,000. Your task is to find the two integers *a* and *b*, where 0 <= *b* < *d* and *ad* + *b* = *n*. You do *not* need to (and shouldn't) simplify the fraction.

A single line containing the integers *n* and *d* separated by a space.

If *b* is not 0, print a single line in the format *a* *b*/*d*.
Otherwise, print *a*.
