您的数组开的太大了捏

@[HCGZS](/user/730477) 您为蛤要开这么大的数组啊?你是因为这个CE掉的，装不下了。一般数组要开在 $1e7$ 及以下啊......

@[HCGZS](/user/730477) 试试把数组调小一点再运行，试试能不能玄学跑过去
by HotDogSeller @ 2022-08-26 21:31:03
不行再调小，知道不是 $MLE$ 为止
by HotDogSeller @ 2022-08-26 21:31:57
我谔谔，map 了解一下？
by EastSnowLotus @ 2022-08-27 07:58:14
@[HCGZS](/user/730477) 还有，您不需要动不动全 at 一遍，总共一次我就可以看得见捏。

玄学这种东西,我还是...
# 信的
只是,这次好像不起作用了
