Modify a data structure : Search Method

The video tutorial explains how to implement a search method for a linked list. It begins by introducing the concept of a search method and its purpose. The tutorial then explains how to set up a current node variable to traverse the linked list, starting from the head node. It provides a detailed explanation of using while loops to iterate through the list, including an example with a counter. Finally, the tutorial demonstrates how to implement the search function, checking if a search value exists in the list and returning the value if found.

What is the primary purpose of the search method in a linked list?

• To delete a node from the list

• To find a specific value in the list

• To sort the list

• To add a new node to the list

Where does the traversal of the linked list start in the search method?

• At a random node

• At the head node

• At the middle node

• At the tail node

What is the role of the 'current node' variable in the search method?

• It stores the search value

• It keeps track of the current position in the list

• It counts the number of nodes

• It holds the previous node's value

How does a while loop function in the context of traversing a linked list?

• It runs until a specific node is found

• It runs indefinitely without stopping

• It runs only once

• It runs as long as the current node is not null

In the counter example, what condition is used to stop the while loop?

• Counter is greater than 10

• Counter is not equal to 10

• Counter is equal to 10

• Counter is less than 10

What happens if the search value is found in the linked list?

• The function continues to the next node

• The function deletes the node

• The function returns the current node's value

• The function returns null

What is returned if the search value is not found in the linked list?

• An error message

• Null

• The last node's value

• The first node's value
