• 【做题】CF239E. k-d-sequence——线段树

    时间:2023-12-14 16:08:20

    首先,容易得到判断一个子串为“good k-d sequence”的方法:子串中没有重复元素,且所有元素模d相等。记mx为除以d的最大值,mn为除以d的最小值,则\(mx-mn<=r-l+k\)。然后,我们对于每一段极大的元素同模的子串,处理\(d=1\)的情况。显然,我们需要枚举一个端点。这...

  • Codeforces Round #529 (Div. 3) E. Almost Regular Bracket Sequence (思维,模拟栈)

    时间:2023-12-05 19:34:49

    题意:给你一串括号,每次仅可以修改一个位置,问有多少位置仅修改一次后所有括号合法.题解:我们用栈来将这串括号进行匹配,每成功匹配一对就将它们消去,因为题目要求仅修改一处使得所有括号合法,所以栈中最后一定会有两个括号剩余,并且这两个括号要么是\(((\)要么是\())\),\()(\)是无论如何都不合...
