# 图算法-树重心(graph-12cd830a)

## When to use

任务「树重心」;对照:树重心——移除后最大子树最小(平衡点)。

## 克制条款(不适用条件)

条件不满足即不适用(负路由:输入不满足生效条件时返回 None/不执行)

## How to execute

后序 DFS 收集 size,比较 max(子树, n-size) 取最小

## Verification

- 单元样例 3 条(cases 断言)
- 物理基底:按 calibration 对照(编译/运行/断言裁决)

## References

- 单元库:graph_db_units.py「图算法-树重心」
