Find the type of array

Given an array, it can be of 4 types
(a) Ascending
(b) Descending
(c) Ascending Rotated
(d) Descending Rotated
Find out which kind of array it is and return the maximum of that array.

// C++ program to find type of array, ascending
// descending, clockwise rotated or anti-clockwise
// rotated.
#include<bits/stdc++.h>
using namespace std;

// Function to find the type of an array
// and maximum element in it.
void findType( int arr[] , int n)
{

    // boolean variables to check if array is increasing or decreasing
    bool isIncreasing = false , isDecreasing = false;
for( int i = 1 ; i < n ; ++i){
   
   // increasing value found
   if(arr[i-1] < arr[i]){
       isIncreasing = true;
       // if the array was decreasing earlier then its Descending Ascending and maximum is current element
       // example :  2 1 5 4 3 
       if(isDecreasing){
           cout << "Descending rotated Max : " << arr[i] << "\n";
           return;
       }
   }
    // decreasing value found
   else if (arr[i-1] > arr[i]){
       isDecreasing = true;
        // if the array was increasing earlier then its Ascending Descending and maximum is i-1 element
        // eg 4 5 1 2 3
       if(isIncreasing){
           cout << "Ascending rotated Max : " << arr[i-1] << "\n";
           return;
       }
       
   }
   
}

// else array is purely ascending or descending
if(isIncreasing)
    cout << "Ascending  Max : " << arr[n-1] << "\n";
else
   cout <<"Descedning Max : " << arr[0] << "\n";
