Sum of Adjacent Distances

Difficulty: easy

Max Points: 10

Description

Write a program to calculate and return the sum of distances between the adjacent numbers In 

an array of positive integers.

Note:

You are expected to write code in the find Total distance function only which receive the first 

parameter as the number of items in the array, and second parameter as the array itself. You are 

not requested to take input from the console.

Constraints

NA

Example

Finding the total distance between adjacent items of a list of 5 numbers

Input:

5

10 11 7 12 14

Output:

12

Explanation

The first parameters (5) is the size of the array next is an array of integers the total of distance is

12 as per the calculation below.

10-11=1

11-7=4

7-12=5

12-14=2

Total distance-1+4+5+2=12
