Array Rotation via Triple Reversal

The Array Rotation via Triple Reversal technique is applied when tackling problems characterized by specific invariants in the problem state or constraints:

• Core Strategy: Rotate an array in place by reversing the whole array and then reversing its two constituent segments.
• 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 Arrays foundations, reducing worst-case algorithmic complexity.
