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;
};
