Efficient Deployments

Problem Overview

• Find an order to deploy n processors in a line to maximize total efficiency given whether 0, 1, or 2 neighbors were deployed before each.
• Input: arrays noAdjacent, oneAdjacent, bothAdjacent (length n); Output: maximum efficiency sum as a long integer.
• Constraints: 1 ≤ n ≤ 1e5; values up to 1e9; endpoints have one neighbor.
• Domain: supercomputer processor scheduling with adjacency-driven efficiency.
• From Snowflake interviews; a coding interview problem and common interview question.
