The Little Elephant loves strings very much.

翻译中…

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).

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

Input

翻译中…

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 $10^{5}$.

Output

翻译中…

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

翻译中…

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.

Note

翻译中…

Let's assume that you are given string $*a* = *a*_{1}*a*_{2}... *a*_{|*a*|}$, then let's denote the string's length as $|*a*|$ and the string's $*i*$-th character as $*a*_{*i*}$.

翻译中…

A substring $*a*[*l*... *r*]$ $(1 ≤ *l* ≤ *r* ≤ |*a*|)$ of string $*a*$ is string $*a*_{*l*}*a*_{*l* + 1}... *a*_{*r*}$.

翻译中…

String $*a*$ is a substring of string $*b*$, if there exists such pair of integers $*l*$ and $*r*$ $(1 ≤ *l* ≤ *r* ≤ |*b*|)$, that $*b*[*l*... *r*] = *a*$.
