哦对提交30分，3个AC，剩下的都TLE，应该就都是死循环了

@[GWBailang](/user/559442) ~~首先，数据可达 $10^6$，建议你使用scanf进行输入~~

@[GWBailang_XHao](/user/964083) 其次？

而且样例2里sf和rd和dian一直都没变
by GWBailang_XHao @ 2023-10-13 19:35:35
@[GWBailang](/user/559442) 等会儿你这代码我还没太看懂
by GWBailang_XHao @ 2023-10-13 19:36:36
@[GWBailang](/user/559442) 也就说明……一直没进39行的if
by GWBailang_XHao @ 2023-10-13 19:39:01
@[GWBailang](/user/559442) 也就进一步说明rd[i]一直大于零
by GWBailang_XHao @ 2023-10-13 19:40:32
@[GWBailang](/user/559442) 所以我觉得问题大概出在前面输入和add的部分

……
by GWBailang @ 2023-10-13 19:41:57
@[GWBailang](/user/559442) 或者就是if的条件写错了
