懒得本地check了，靠CI https://github.com/duangsuse/tv/actions/runs/16111998058/job/45457458405 试错

这两天时间多但是效率低
真的被恶心死了

Hoare三元组的一般形式为{ P } S { Q }，其中P和Q是断言（assertions），分别称为前置条件（precondition）和后置条件（postcondition），S是一个程序语句或程序段。
含义
{ P } S { Q }表示如果在执行语句S之前，程序的状态满足前置条件P，并且语句S正常终止，那么在语句S执行完毕后，程序的状态将满足后置条件Q。也就是说，前置条件描述了执行语句S之前程序应满足的状态，后置条件描述了执行语句S之后程序应达到的状态。
