Problem

Team Redshift had just arrived at Suvarnabhumi International Airport to take part in the ICPC Bangkok Regional when they could not believe their eyes. The large screen at the airport said the current year was 2562.

Thailand, a Buddhist country, uses the Buddhist calendar, which counts years from the year of Buddha's parinirvana. Korea, on the other hand, uses the Gregorian calendar. Given a Buddhist calendar year, write a program that converts it to a Gregorian calendar year.

Input

A Buddhist calendar year y to convert is given. (1000 ≤ y ≤ 3000)

Output

Print the result of converting the Buddhist calendar year to a Gregorian calendar year.
