题意: 给两个水果名,要求他们的LCS部分只输出1次,其他照常输出,但是必须保持原来的顺序! 思路: 求LCS是常规的,但是输出麻烦了,要先求LCS,再标记两串中的所有LCS字符,在遇到LCS字符时,先输串1的,再输串2的,然后输该字符,以保证每个LCS字符输出前,两串中该字符前面的字符全部已输出. //#pragma comment(linker,"/STACK:102400000,102400000") #include <iostream> #include <…

题意: 将两个英文单词进行合并.[最长公共子串只要保留一份] 输出合并后的英文单词. 思路: 求最长公共子串. 记录路径: mark[i][j]=-1:从mark[i-1][j]转移而来. mark[i][j]=0:从mark[i-1][j-1]转移而来. mark[i][j]=1:从mark[i][j-1]转移而来. 代码: char s1[105], s2[105]; int dp[105][105]; int mark[105][105]; void print(int x,int y){…

题意:给定两个字符串,让你求一个最短的字符串,并且这个字符串包含给定的两个. 析:看到这个题,我知道是DP,但是,不会啊...完全没有思路么,我就是个DP渣渣,一直不会做DP. 最后还是参考了一下题解,主要是这样的,要想最短,就必须让两个字符串重复的最多,也就是LCS, 然后把剩下的不相同的字符再给补上,说起来容易,实现起来,难!反正对我来说是难. 然后根据LCS的原理,我们对这个两字符串,进行标记,什么意思呢,就是说,如果某个字符是公共字符, 等到输出时,我们只输出一次,而对于不是公共的,我们…
