School Accuracy: 28.65% Submissions: 526 Points: 0

Given an array arr[] of size N, check if it is sorted in non-decreasing order or not. 

Example 1:

Input:
N = 5
Arr[] = {10, 20, 30, 40, 50}
Output: 1
Explanation: The given array is sorted.

Example 2:

Input:
N = 6
Arr[] = {90, 80, 100, 70, 40, 30}
Output: 0
Explanation: The given array is not sorted.


Your Task:
You don't need to read input or print anything. Your task is to complete the function arraySortedOrNot() which takes the arr[] and N as input parameters and returns a boolean value (true if it is sorted otherwise false).


Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)


Constraints:
1 ≤ N ≤ 105
1 ≤ Arr[i] ≤ 106
