# Implementing the task with module datetime
import datetime

# Input the string with date in format - year month day
date = [int(i) for i in input().split()]

# Converting and saving the format date in the class datetime.date
current_date = datetime.date(date[0], date[1], date[2])

# Input the amount of days to add to the saved date
add = int(input())

# Converting the adding days into the date format
add_days = datetime.timedelta(add)

# Calculating the final result
future_date = current_date + add_days

# Showing the final date
print(future_date.year, future_date.month, future_date.day)
