Given a singly linked list, delete all occurrences of a given key in it. For example, consider the following list.
Input: 2 -> 2 -> 1 -> 8 -> 2 -> 3 -> 2 -> 7 Key to delete = 2 Output: 1 -> 8 -> 3 -> 7
This is mainly an extension of this post which deletes first occurrence of a given key.
We need to first check for all occurrences at head node and change the head node appropriately. Then we need to check for all occurrences inside a loop and delete them one by one. Following is C implementation for the same.
Created Linked List: 2 2 1 8 2 3 2 7 Linked List after Deletion of 1: 1 8 3 7
