/*Given an array a, your task is to output an array b of the same length by applying the following transformation: 
– For each i from 0 to a.length - 1 inclusive, b[i] = a[i - 1] + a[i] + a[i + 1]
– If an element in the sum a[i - 1] + a[i] + a[i + 1] does not exist, use 0 in its place
– For instance, b[0] = 0 + a[0] + a[1]

Example

For a = [4, 0, 1, -2, 3]: 
– b[0] = 0 + a[0] + a[1] = 0 + 4 + 0 = 4
– b[1] = a[0] + a[1] + a[2] = 4 + 0 + 1 = 5
– b[2] = a[1] + a[2] + a[3] = 0 + 1 + (-2) = -1
– b[3] = a[2] + a[3] + a[4] = 1 + (-2) + 3 = 2
– b[4] = a[3] + a[4] + 0 = (-2) + 3 + 0 = 1

So, the output should be solution(a) = [4, 5, -1, 2, 1].
