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.
