模式摘要

先识别什么

题目里常出现可以复用的状态更新节奏。

解法节奏

先口述状态和不变量,再解释每一步如何更新,最后用反例验证边界。

高频失分点

状态定义说不清,写出来也难以稳定维护。

识别信号

  • 题目里常出现可以复用的状态更新节奏。
  • 暴力枚举太慢,但结构上存在可维护的不变量。
  • 面试追问通常会盯住边界、状态变更和复杂度。

解题流程

  1. 1. 明确窗口/状态定义
  2. 2. 更新状态并维护约束
  3. 3. 用边界样例验证

常见失分点

  • 状态定义说不清,写出来也难以稳定维护。
  • 只会背模板,解释不了为什么这样更新。
  • 样例能过,但边界和复杂度追问容易崩。
