340 - Master-Mind Hints /*读了老半天才把题读懂,读懂了题输出格式没注意,结果re了两次. 题意:先给一串数字S,然后每次给出对应相同数目的的一串数字Si,然后优先统计Si和S对应位相同并且相等的个数L,在统计不在对应位上但相等的的个数R. 当Si全0时,表示结束. 每个数只能用一次. 例如:有 S 1 3 5 5 S1 1 1 2 3 S2 4 3 3 5 Si . . . . 0 0 0 0 对于S1:则第一步只有第一个对应相等,所以L = 1 就还剩下3 5 5 1…

题意:给出N个数,要求把它们拼凑起来,让得到的数值是最大的. 只要分别比较两个数放前与放后的值的大小,排序后输出就可以了. 比如123和56,就比较12356和56123的大小就行了. 写一个比较函数,然后用sort调用就行了. 刚开始时用long long做,每次比较都让数相连,然后比较大小,后来发现数据好像会很暴力,即使longlong也不够大. 考虑到两个数相连后两种情况长度都一样,所以只要把数值当成string来做就行了,比较两个string的字典序大小. 代码: /* * Author…

这道题貌似可以用滑动窗口或者单调栈做, 但是我都没有用到. 这道题要求连续子序列中和乘上最小值最大, 那么我们就可以求出每一个元素, 以它为最小值的的最大区间的值, 然后取max就ok了.那么怎么求呢? 我可以初始化出一个第一个小于当前元素的的元素的位置, 也就是说初始化出以当前元素为最小值的 左右端点, 求出之后枚举一遍就ok了. 那么关键是怎么求呢? 这里有一点扫描法的味道. 假设当前序列为1243 以求右端点为例, 右端点的位置也就是在右侧第一个小于当前元素的元素的位置. 那么如果序列是递…
