EIINCRDES - Order of the sequence |
Given an array of length n. Check if the array is strictly increasing or strictly decreasing. An array, named A is strictly increasing if A[i] > A[i-1] for every i ≥ 1
Input
The first line contains the length of the array n (1< n ≤ 105)
The second line contains n integers which are elements of the array, respectively.
Output
If the given array is strictly increasing, output “increasing”.
If the given array is strictly decreasing, output “decreasing”, otherwise output “none”.
