15 Removing Nodes From Linked List
Problem Statement
Write Recursive Approach for Removing Nodes From Linked List.
Given a singly linked list and a target value, write a recursive algorithm to remove all nodes from the linked list that have the target value.
Examples:
| Sr # | Input | Expected Output | Description |
|---|---|---|---|
| 1 | 1 -> 2 -> 3 -> 4 -> 2 | 1 -> 3 -> 4 | Remove all nodes with value 2 from the list. |
| 2 | 2 -> 2 -> 2 -> 2 -> 2 | null | Remove all nodes with value 2 from the list. |
| 3 | 1 -> 3 -> 5 -> 7 | 1 -> 3 -> 5 -> 7 | No nodes with value 2 exist in the list. |
Constraints:
- The number of the nodes in the given list is in the range [1, 105].
- 1 <= Node.val <= 105

🎨 Explain it visually
Build the mental picture, not memorization.
I just read a lesson on **15 Removing Nodes From Linked List** (DSA) and want to truly understand it. Explain 15 Removing Nodes From Linked List from first principles using ONE vivid real-world analogy and a visual mental model — draw it as ASCII art or a clear step-by-step diagram — with a concrete example using real numbers. Then ask me one question to check I got the mental picture, and wait for my reply. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🤔 Walk me through it (interactive)
Socratic — adapts to where you're stuck.
Teach me **15 Removing Nodes From Linked List** interactively. Ask me ONE guiding question at a time, wait for my answer, and adapt to my confusion — build the idea with me step by step instead of explaining it all at once. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧪 Quiz me & fix my gaps
Active recall exposes what you missed.
Quiz me on **15 Removing Nodes From Linked List** with 5 questions, easy to tricky, ONE at a time. Tell me if each answer is right; at the end, explain clearly what I got wrong and why. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
