There are two interesting things in physics, they are:

Distance: Distance is the total length covered by a moving object irrespective of the direction of motion. Here only magnitude is needed.

Displacement: Displacement is distance measured in a straight line and in a specified direction. So both magnitude and direction are important. For example:

A car travels 5 km to east and makes a U-turn back to travel a further distance of 3 km. Then: 

I.  Distance Covered: 5 + 3 = 8 km    II. Displacement: 5 - 3 = 2 km

As a programmer write a program that will be used to find distance & displacement of a given entity

Input Format

The first line of input will contain a number N (1<=N<=100), which will denote the number of sample we want to take. The rest lines contain distance and sign of distance for N times. 

Output Format

In output there will be two lines. The first line contains total distance covered by the object and the second line contains the displacement of the object.
