Question
In linked list implementation of a queue, where does a new element be inserted?
Solution
In a linked list implementation of a queue, a new element is always inserted at the end of the list. Here are the steps:
- Create a new node with the given value.
- If the queue (linked list) is empty, set the new node as the front and rear of the queue.
- If the queue is not empty, add the new node at the end of the queue (linked list). This is done by setting the 'next' of the current rear node to the new node, and then updating the rear pointer to the new node.
- Update the size of the queue.
