Introduction : Recursion can feel tricky in Linked List problems because the list is naturally recursive — each node points to the next. Once you understand this property, many problems become cleaner and more elegant to solve recursively.

In this post, I’ll share how recursion helps simplify complex Linked List logic — using LeetCode 2487: Remove Nodes from Linked List as an example.

Core Idea : Instead of moving forward and worrying about the “next” nodes,
recursion allows us to move backward — by first solving for the tail, and then deciding what to do with the current node as we backtrack.

Think of it like this:

"Solve the rest of the list first, then decide whether to keep or remove the current node."

Try Recursion On These Next :
LeetCode 206 – Reverse Linked List
LeetCode 203 – Remove Linked List Elements
LeetCode 234 – Palindrome Linked List
LeetCode 2487 – Remove Nodes from Linked List (this one!)
LeetCode 876 – Middle of Linked List

Please try to solve these using recursion, if possible.

Final Outcome : Recursion is not just a coding trick — it’s a mindset.
Once you start thinking “solve the smaller list first,” Linked List problems start to feel elegant and logical.
