trionic·数组·ii·core·interview·pattern 模式
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
- Look for the candidate's understanding of dynamic programming in solving subarray problems.
- Evaluate how well the candidate optimizes their approach using techniques like prefix sum or sliding windows.
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
- Not recognizing the need for dynamic programming, leading to inefficient brute force solutions.
