LCS2 - Longest Common Substring II


A string is finite sequence of characters over a non-empty finite set Σ.

In this problem, Σ is the set of lowercase letters.

Substring, also called factor, is a consecutive sequence of characters occurrences at least once in a string.

Now your task is a bit harder, for some given strings, find the length of the longest common substring of them.

Here common substring means a substring of two or more strings.

Input

The input contains at most 10 lines, each line consists of no more than 100000 lowercase letters, representing a string.

Output

The length of the longest common substring. If such string doesn't exist, print "0" instead.

Example

Input:
alsdfkjfjkdsal
fdjskalajfkdsla
aaaajfaaaa

Output:
2

Notice: new testcases added

Can I use "while(scanf("%s",ch))!=EOF)" for input?
It was always TLE...

WA on #10, because I forget to update information on the parent tree

never mind, submitted, passed until 10 and TLE

why in the test case the answer is 2?
in second and third line there is the substring "ajf" of length 3!!!!

I don't know why am I getting WA on TEST 15???

I found a wrong way to pass the current testcases, and I have found a new testcase can make it WA. Could I submit the new testcase or do something?

i submited the same solution that has got AC when i used it in the easier version of this problem but now
i got WA on #10 ... does that mean there is something wrong with the testcases of the easier version or what ?
