Check Sorted Order

Given an integer (n) representing the number of elements in an array and the array itself, determine whether the array is sorted in non-decreasing order. If the array is sorted, output Sorted; otherwise, output Unsorted.

In mathematical terms, for an array (a_1, a_2, \ldots, a_n), check whether (a_i \leq a_{i+1}) holds for all (1 \leq i < n).

inputFormat

The input consists of two lines:
1. The first line contains an integer (n) (where (1 \leq n \leq 10^5)), the number of elements in the array.
2. The second line contains (n) space-separated integers (a_1, a_2, \ldots, a_n) (each satisfying (-10^5 \leq a_i \leq 10^5)).

outputFormat

Output a single line containing Sorted if the array is in non-decreasing order, or Unsorted otherwise.## sample
