Take/Skip Adjacent-Constraint DP

The Take/Skip Adjacent-Constraint DP technique is applied when tackling problems characterized by specific invariants in the problem state or constraints:

• Core Strategy: DP where taking an element forbids taking its immediate neighbor, tracking best-with/without-current at each step.
• 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 Dynamic Programming foundations, reducing worst-case algorithmic complexity.
