Transcribed Image Text:**Title: Removing Nodes with Duplicate Keys in a Linked List** **Objective:** Learn to construct a program that removes all nodes in a linked list with duplicate keys. **Description:** The task involves creating a function or program that identifies and removes all nodes within a linked list that share the same key. A linked list is a data structure where elements, called nodes, are connected using pointers. **Steps:** 1. **Traversal**: Start from the head of the linked list and iterate through each node. 2. **Identification**: For each node, check if there are other nodes with the same key. 3. **Removal**: If duplicate keys are found, remove all nodes associated with that key from the list. 4. **Re-linking**: Ensure the nodes are re-linked correctly to maintain the integrity of the linked list. **Note:** This approach may require using additional data structures (e.g., hash tables) to store and track key occurrences. **Application:** This algorithm is useful in situations where unique keys are required, such as in databases or inventory systems. **Learning Outcomes:** By following this guide, learners will understand how to manipulate data in a linked list and handle duplicate entries efficiently.
