题意:给你一个字符串,问你含有 k个字符集合 长度最短的不是字符串子序列的种类数和长度。解题思路:DP.很难想 site[i] 表示以i 开头的使得 串不再字符串中的最小长度 ,dp[i] 表示种类数。 状态转移方程在代码里面。解题代码: 1 // File Name: j.4.cpp 2 //.....

题目大意:给出n个数,从中选取k个,使得乘积最大,并且尽量使和最大分析:首先按照数的绝对值大小排序。然后就要分三大类情况讨论:(1)前k个中选到0:如果选到0的话,乘积一定是0,所以尽量选大的数,让和变大。(2)前k个中选到负数的个数为偶数:这样的话直接输出答案(一定为最优解)(3)前k个中选到的负...
