P2693 [USACO1.3]号码锁 Combination Lock 题目描述 农夫约翰的奶牛不停地从他的农场中逃出来,导致了很多损害.为了防止它们再逃出来,他买了一只很大的号码锁以防止奶牛们打开牧场的门. 农夫约翰知道他的奶牛很聪明,所以他希望确保它们不会在简单地试了很多不同的号码组合之后就能轻易开锁.锁上有三个转盘,每个上面有数字1..N (1 <= N <= 100),因为转盘是圆的,所以1和N是相邻的.有两种能开锁的号码组合,一种是农夫约翰设定的,还有一种“预设”号码组合是锁匠设定…

题目 题目描述 农夫John的牛从农场逃脱出去了,所以他决定用一个密码锁来把农场的门锁起来,这个密码锁有三个表盘,每个表盘都是环形的,而且上面刻有1~N,现在John设了一个开锁密码,而且这个锁的设计者也有一个开锁密码.这个锁有一个特点,那就是它的容错方式,当我们输入密码时,如果我们的密码与正确的开锁密码相比较,对应的每一个表盘上的数字的距离都相差不超过2时,这个密码便可以打开这个锁. 例如:John设定的开锁密码为(1,2,3),锁的设计者的开锁密码为(4,5,6).如果我们现在将锁设定为(1…

题意:给出一个由26个小写字母组成的字符串,可以任意地进行若干个操作,每次操作是让指定区间内的字母变为下一个字母(z变成a).问是否存在方案使得这个字符串变为回文串. 一开始的想法是构造len/2条模26意义下方程,但由于26不是质数,判断有没有解并不容易.(下文自动省略模26) 我们发现,一次操作对于方程组的影响大概是这样的: 如上图所示,一次对区间[l,r]进行的操作,其中从一端到其关于中点的对称点的区间实质是没有贡献的.(上图中为区间[l,l'])同样地,对于完全位于中点右边的区间,可以将…

一.题目大意 模拟一个开组合的密码锁过程.就像电影你开保险箱一样,左转几圈右转几圈的就搞定了.这个牌子的锁呢,也有它独特的转法.这个锁呢,有一个转盘,刻度为0~39.在正北方向上有一个刻度指针.它的密码组合有三个数,开锁的套路为:先把刻度盘顺时针转两圈,然后再顺时针转到第一个数,再把刻度盘逆时针转一圈,再逆时针转到第二个数,最后再顺时针转到第三个数.这里的转到那个数是指将刻度盘上的数转到指针处.起始位置和组合密码有标准输入给出.求圆盘转过的总度数(顺时针加上逆时针).注意刻度盘上还有一个凸起的圆…

Content 有一个锁,它只有指针再次指到 \(0\) 刻度处才可以开锁(起始状态如图所示,一圈 \(360\) 度). 以下给出 \(n\) 个操作及每次转动度数,如果可以通过逆时针或顺时针再次转到 \(0\) 度输出 YES,否则输出 NO. 数据范围:\(1\leqslant n\leqslant 15\),\(1\leqslant a_i\leqslant 180\). Solution 不知道为什么 19 年 4 月就做了这题,现在看到这题想写篇题解,于是就有了这篇题解( 我们一看到…
