Efficient Deployments

Problem Overview

• Core task: Determine an order to deploy n processors in a row to maximize total efficiency.
• Inputs/Output: arrays no_adjacent, one_adjacent, both_adjacent; return a long integer max sum.
• Rules: Each processor’s efficiency depends on 0, 1, or 2 deployed neighbors; ends have one neighbor; 2≤n≤1e5, values up to 1e9.
• Context: Scheduling deployments in a supercomputer line.
• Source: Snowflake coding interview; an interview question problem.
