Linked List Partition / Splice

The Linked List Partition / Splice technique is applied when tackling problems characterized by specific invariants in the problem state or constraints:

• Core Strategy: Splice a linked list into separate chains by a pivot condition, then reconnect them in the required order.
• When to use: Look for opportunities where repeated re-computation can be replaced by maintaining monotonic properties, state windows, or relational pointers.
• Interview Signal: Demonstrating this pattern shows mastery of Linked List foundations, reducing worst-case algorithmic complexity.
