You are given n strings ti. Each string has cost ci.
Let's define the function of string , where ps, i is the number of occurrences of s in ti, |s| is the length of the string s. Find the maximal value of function f(s) over all strings.
Note that the string s is not necessarily some string from t.
The first line contains the only integer n (1 ≤ n ≤ 105) — the number of strings in t.
Each of the next n lines contains contains a non-empty string ti. ti contains only lowercase English letters.
It is guaranteed that the sum of lengths of all strings in t is not greater than 5·105.
The last line contains n integers ci ( - 107 ≤ ci ≤ 107) — the cost of the i-th string.
Print the only integer a — the maximal value of the function f(s) over all strings s. Note one more time that the string s is not necessarily from t.
