题目:rnrnA subsequence of a given sequence is the given sequence with some elements (possible none) left out. Given a sequence X = another sequence Z = is a subsequence of X if there exists a strictly increasing sequence of indices of X such that for all j = 1,2,...,k, xij = zj. For example, Z = is a subsequence of X = with index sequence <1, 2, 4, 6>. Given two sequences X and Y the problem is to find the length of the maximum-length common subsequence of X and Y.rnrnThe program input is from a text file. Each data set in the file contains two strings representing the given sequences. The sequences are separated by any number of white spaces. The input data are correct. For each set of data the program prints on the standard output the length of the maximum-length common subsequence from the beginning of a separate line.rnrnSample Inputrnrnabcfbc abfcabrnprogramming contest rnabcd mnprnrnSample Outputrnrn4rn2rn0rnrnrnrnrnrnrnrnrnrn一下是我的答案,对这些数据没有错误,但是提交就是wa....rnrnrnrn#includern#includernusing namespace std;rnint main()rnrn string a,b;rn int i,j,alen,blen,cnt,p;rn while(cin>>a>>b)rn rn cnt=0;rn p=0;rn rn alen=a.size();rn blen=b.size();rn for(i=0;i

Contest time again! How excited it is to see balloons floating around. But to tell you a secret, the judges' favorite time is guessing the most popular problem.

Each test case starts with a number N (0 < N <= 1000) -- the total number of balloons distributed. The next N lines contain one color each.
