Can somebody write the isSorted function

Write a member function named isSorted that could be added to the LinkedIntList class. Your function should return true if the list is in sorted (non-decreasing) order and false otherwise. An empty list is considered to be sorted.

Constraints: Do not call any methods of the LinkedIntList class. Do not construct any new ListNode objects in solving this problem (though you may create as many ListNode* pointer variables as you like). Do not use any auxiliary data structures to solve this problem (no array, vector, stack, queue, string, etc). Your member function should not modify the linked list's state; the state of the list should remain constant with respect to your function. You should declare the function to indicate this to the caller.

Write the member function as it would appear in LinkedIntList.cpp. You do not need to declare the function header that would appear in LinkedIntList.h. Assume that you are adding this method to the LinkedIntList class as defined below:

class LinkedIntList {

private:

 ListNode* front; // nullptr for an empty list

 ...

};

struct ListNode {

 int data;

 ListNode* next;

};
