Greedy Farthest-Reach Tracking

The Greedy Farthest-Reach Tracking technique is applied when tackling problems characterized by specific invariants in the problem state or constraints:

• Core Strategy: Greedily track the farthest index reachable so far while scanning left to right to decide feasibility or minimum jumps.
• 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 Greedy foundations, reducing worst-case algorithmic complexity.
