The first number is n, then n integers. Print them in reverse order, space-separated.
std::reverse edits the vector in place.
Input. n, then n integers.
Output. The values in reverse order, space-separated.
Constraints
- 1 ≤ n ≤ 1000
Examples
Input
5 1 2 3 4 5
Output
5 4 3 2 1
Hint
- std::reverse(v.begin(), v.end()); then print each value.
