An array is a type of data structure that stores elements of the same type in a contiguous block of memory. In an array, , of size , each memory location has some unique index, (where ), that can be referenced as (you may also see it written as ).
Given an array, , of integers, print each element in reverse order as a single line of space-separated integers.
Note: If you've already solved our C++ domain's Arrays Introduction challenge, you may want to skip this.
Input Format
The first line contains an integer, (the number of integers in ).
The second line contains space-separated integers describing .
Constraints
Output Format
