Question
Java - numList: 52, 89 ListInsertAfter(numList, node 89, node 20) ListInsertAfter(numList, node 52, node 10) ListInsertAfter(numList, node 52, node 26)

Transcribed Image Text:**Linked List Insertion Operations**
The text provides a sequence of operations applied to a linked list and poses questions regarding the pointer directions of nodes. Here's a detailed breakdown:
1. **Initial List:**
- `numList: 52, 89`
This indicates that the initial linked list contains two nodes with values 52 and 89.
2. **Insertion Operations:**
Three `ListInsertAfter` operations are performed on `numList`, described as follows:
- `ListInsertAfter(numList, node 89, node 20)`
Inserts a new node with value 20 after the node containing 89.
- `ListInsertAfter(numList, node 52, node 10)`
Inserts a new node with value 10 after the node containing 52.
- `ListInsertAfter(numList, node 52, node 26)`
Inserts a new node with value 26 after the node containing 52. This might change the existing nodes' connections based on list implementation.
3. **Current List State:**
An input field labeled `numList is now:` allows users to type the updated sequence of node values separated by commas. An example (`Ex: 1, 2, 3`) illustrates the format.
4. **Follow-up Questions:**
Two selection prompts ask about the pointers of node 26:
- "What node does node 26's next pointer point to?"
- "What node does node 26's previous pointer point to?"
Each question has a dropdown menu labeled `Select`, likely allowing users to choose from a list of node values.
This educational content helps users understand linked list operations, particularly how insertions affect node connections.
