﻿Array Element Adjacent Sum
Given an Array of length N, the program must print the sum of adjacent numbers of elements present in the array.
Input Format:
First line contains N.Second line contains N element values seperated by a space.
Output Format:
Adjacent sum of N elements seperated by a space.
Boundary Conditions:2 <= N <= 100
