题目描述

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.
