Print Fibonacci Series in reverse order

Given a number n then print n terms of fibonacci series in reverse order.

Examples:

Input : n = 5
Output : 3 2 1 1 0

Input : n = 8
Output : 13 8 5 3 2 1 1 0


Algorithm

1) Declare an array of size n.
2) Initialize a[0] and a[1] to 0 and 1 respectively.
3) Run a loop from 2 to n-1 and store
sum of a[i-2] and a[i-1] in a[i].
4) Print the array in the reverse order.
