removeAll

Language/Type: C++ linked lists pointers

Write a member function named removeAll that could be added to the LinkedIntList class. Your function should accept an integer parameter and remove all occurrences of that value. You must preserve the original order of the remaining elements of the list. For example, if a variable named list contains the following values:

{3, 9, 4, 2, 3, 8, 17, 4, 3, 18}

Then the call of list.removeAll(3); would remove all occurrences of the value 3 from the list, yielding the following values:

{9, 4, 2, 8, 17, 4, 18}

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).

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;
};
Member function: Write a member function that will become part of an existing class. You do not need to write the complete class.
