今天常州某区程序设计小能手选拔赛的E题我写的程序本是满分的
但现场只得了10分
刚才才发现是把endl漏了。
所以输出是一对NO和YES
这么说，我如果写了endl，总分应是500分
可以得到第6名
而事实只有第11名
本来能加点rating
现在却扣了一堆

长教训了，忘记endl扣了138rating！！！

#2488题题目描述不严谨
2023-05-21 16:05:03 By 李凌宇
2488的题目描述是这样说的
维护序列。给定一个长度为n的整数序列。现在有m个操作，操作分为三类，格式如下：
1 i：询问序列中第i个元素的值；
2 i v：在序列中第i个元素前加入新的元素v,如果添加的位置错误，输出Insert error!!!；
3 i：删除序列中的第i个元素，如果删除的位置错误，输出Delete error!!!。但大家请注意
它询问序列中第i个元素的值的时候有可能范围太小或太大（test 9） 所以大家请在输出的时候注意一下

l[0]=l1;

return 0;
}
idx++;
time1=0,time2=0;
}
return 0;
}请问出什么问题了？
包括别人也出过这样的问题
例：Joker任务调度比赛时0分，比赛完之后在提交100分
请问此问题能改吗？

请问四月月赛一难吗？
759截止我写这个文章时是不对的（2023年3月25日20点05分）
2023-03-25 20:08:25 By 李凌宇
当前（2023年3月25日20点05分），759的测试用例4和5的答案都是Bad placement.，但，这是不对的。
它们的正确答案应该是There are 134 ships.和There are 182 ships.
用例4的输入：
