wrong test case!

Posted by majia_ at 2009-04-05 14:42:14 on Problem 3729
5 5 2
1 2 1 2 3
1 2 3 4 5

答案应该是1,而不是2
因为
the extended string of S3 should NOT be the substring of S2.
而且if S3 does not have a succeed character in S1, the extended string of S3 is just S3
那么只有第一次出现的1 2满足条件
最后的2 3,其extended string是2 3,不满足条件
