A8613 | Little Elephant and Strings

The Little Elephant loves strings very much.

He has an array $a$ from $n$ strings, consisting of lowercase English letters. Let's number the elements of the array from 1 to $n$ , then let's denote the element number $i$ as $a_{i}$ . For each string $a_{i}$ $(1<=i<=n)$ the Little Elephant wants to find the number of pairs of integers $l$ and $r$ $(1<=l<=r<=|a_{i}|)$ such that substring $a_{i}[l...\ r]$ is a substring to at least $k$ strings from array $a$ (including the $i$ -th string).

Help the Little Elephant solve this problem.

If you are not familiar with the basic notation in string problems, you can find the corresponding definitions in the notes.

The first line contains two space-separated integers — $n$ and $k$ $(1<=n,k<=10^{5})$ . Next $n$ lines contain array $a$ . The $i$ -th line contains a non-empty string $a_{i}$ , consisting of lowercase English letter. The total length of all strings $a_{i}$ does not exceed $10^{5}$ .

On a single line print $n$ space-separated integers — the $i$ -th number is the answer for string $a_{i}$ .

Please, do not use the %lld specifier to read or write 64-bit integers in С++. It is preferred to use the cin, cout streams or the %I64d specifier.
