# Meteomeasurements

Alex is studying in the fifth grade and is going to be a meteorologist. Alex recently started a diary, where he wrote the daily temperature in his own town. Alex found the historical data for the past several hundred years, which means that he has a lot of data. Alex asks you to write a program that calculates the average temperature during **k** consecutive days, and he needs these values for the entire observation period:

- Average temperature from
**1**-st till**k**-th day - Average temperature from
**2**-nd till (**k**+**1**)-th day - and so on until he has data.

And after all these calculated values Alex needs only two numbers - the minimum and maximum values. Help Alex and write the program for him.

#### Input

First line contains two integers **n** and **k** - the number of temperature measurements and the number of days to calculate the average temperature (**1** ≤ **k** ≤ **n** ≤ `10`

). Next line contains ^{5}**n** integers - the temperature measurements. Each of these numbers is in the range (**-100**, **100**).

#### Output

Print two lines that contains minimum and maximum average temperature, calculated on segments of size **k**. Round the answer to the nearest integer.
