threshold majority queries 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
- Focus on how the candidate handles the query sorting and efficient sliding window techniques.
- Look for an understanding of advanced query optimization methods like sqrt decomposition.
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
- Failure to handle overlapping subarrays efficiently, leading to high time complexity.
