Problem: 

**Introduction**:
The "Manhattan Distance" is the distance between two points in an N dimensional space. In simple terms, it is the sum of absolute differences between the measures in all dimensions of two points.

2D Example:
Point1: (x1, y1) Point2: (x2, y2) Manhattan Distance: |x1-x2| + |y1-y2|;

3D Example:
Point1: (x1, y1, z1) Point2: (x2, y2, z2) Manhattan Distance: |x1-x2| + |y1-y2| + |z1-z2|

**Challenge**:
Given two points A and B, calculate the Manhattan Distance between them.
Input
Line 1 : N an integer, the number of dimensions.
Line 2 : N integers, the coordinate of point A.
Line 3 : N integers, the coordinate of point B.
Output
An integer answer, the manhattan distance between A and B.
Constraints
1 ≤ N ≤ 10
-1000 ≤ coordinates ≤ 1000
Example
Input
2
0 0
2 2
Output
4



Solution: 

const N = parseInt(readline());
var inputs = readline().split(' ');
var inputs2 = readline().split(' ');
var sum = 0
for (let i = 0; i < N; i++) {
    const ai = parseInt(inputs[i]);
    const bi = parseInt(inputs2[i]);
    sum += (Math.abs(ai-bi))
}

console.log(sum);
