Everyone knows LCS problem:
str1 = "GCTAT"
str2 = "CGATTA"
the longest common subsequence is "GTT" of them.So you should print "3".
I'm sure you can easily sovle it.So the challenge is coming again.(^_^)
For each case,there are two lines.one is string A,the other is string B.
the string Process to end of file.Each string will have at most 30000 characters.
All the characters are in upper-case.
For each case, output the maximum-length common subsequence.
