1 道题目
模式页适合用来建立可复用解题框架。先识别题目特征，再按固定流程解释状态定义、转移和边界。
识别信号
- Checks if you can identify that sorting and prefix/suffix arrays reduce brute force pairing.
- Looks for correct handling of ride order permutations to minimize total finish time.
解题流程
- 1. 明确窗口/状态定义
- 2. 更新状态并维护约束
- 3. 用边界样例验证
常见失分点
- Failing to consider both ride order possibilities can give a suboptimal finish time.
