HDU-1423-Greatest Common Increasing Subsequence-最长公共上升子序列【模版】

This is a problem from ZOJ 2432.To make it easyer,you just need output the length of the subsequence.

InputEach sequence is described with M - its length (1 <= M <= 500) and M integer numbers Ai (-2^31 <= Ai < 2^31) - the sequence itself.Outputoutput print L - the length of the greatest common increasing subsequence of both sequences.Sample Input

1

5
1 4 2 5 -12
4
-12 1 2 4

Sample Output

2

注意一下控制格式
