很奇怪，一会儿#6RE,#7RE，一会儿#6RE,#7WA,一会儿#6WA,#7RE,一会儿#6WA,#7WA. #6WA,#7WA:https://www.luogu.com.cn/record/200038303 #6WA,#7RE:https://www.luogu.com.cn/record/200038429 #6RE,#7RE:https://www.luogu.com.cn/record/200038865 #6RE,#7WA:https://www.luogu.com.cn/record/200039100 都是同样的代码，数据下载了，本地输出没错，但洛谷错了。 ** code **
