- Objective
- Today, we’re learning about the Array data structure. Check out the Tutorial tab for learning materials and an instructional video!
- Task
- Given an array, A, of N integers, print A’s elements in reverse order as a single line of space-separated numbers.
Input Format
- The first line contains an integer, N (the size of our array).
- The second line contains space-separated integers describing array ‘s elements.
- Constraints
- 1 <= N <= 1000
- 1 <= Ai <= 10000, where Ai is the ith integer in the array.
Output Format
- Print the elements of array A in reverse order as a single line of space-separated numbers.
