Multiplication of previous and next

Given an array of integers A, update every element with multiplication of previous and next
elements with following exceptions.
a) First element is replaced by multiplication of first and second.
b) Last element is replaced by multiplication of last and second last.

Input Format

The only argument given is the integer array A.

Output Format

Return the updated array.

Constraints

1 <= length of the array <= 100000
-10^4 <= A[i] <= 10^4 

For Example

Input 1:
    A = [1, 2, 3, 4, 5]
Output 1:
    [2, 3, 8, 15, 20]

Input 2:
    A = [5, 17, 100, 11]
Output 2:
    [85, 500, 187, 1100]

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
