DZY loves collecting special strings which only contain lowercase letters. For each lowercase letterc DZY knows its value
wc. For each special strings = s1s2...s|s|
(|s| is the length of the string) he represents its value with a functionf(s), where



Now DZY has a string s. He wants to insertk lowercase letters into this string in order to get the largest possible value of the resulting string. Can you help him calculate the
largest possible value he could get?

Input
The first line contains a single string s (1 ≤ |s| ≤ 103).

The second line contains a single integer k (0 ≤ k ≤ 103).

The third line contains twenty-six integers from wa towz. Each such number is non-negative and doesn't
exceed1000.

Output
Print a single integer — the largest possible value of the resulting string DZY could get.

Sample test(s)

Input

abc
3
1 2 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

Output

41

Note
In the test sample DZY can obtain "abcbbc",value = 1·1 + 2·2 + 3·2 + 4·2 + 5·2 + 6·2 = 41.
