min

Language/Type: C++ linked lists pointers
Author: Marty Stepp (on 2016/08/27)

Write a function named min that accepts a pointer to a ListNode representing the front of a linked list. Your function should return the minimum value in the linked list of integers. If the list is empty, you should throw a string exception.

Constraints: 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 function should not modify the linked list's state; the state of the list should remain constant with respect to your function.

Assume that you are using the ListNode structure as defined below:

struct ListNode {
    int data;         // value stored in each node
    ListNode* next;   // pointer to next node in list (NULL if none)
}
Type your C++ solution code here:


This is a function problem. Write a C++ function as described. Do not write a complete program; just the function(s) above.
