standard inputoutput

standard outputYou are given *n* sequences. Each sequence consists of positive integers, not exceeding *m*. All integers in one sequence are distinct, but the same integer may appear in multiple sequences. The length of the *i*-th sequence is *k*_{i}.

Each second integers in each of the sequences are shifted by one to the left, i.e. integers at positions *i* > 1 go to positions *i* - 1, while the first integers becomes the last.

Each second we take the first integer of each sequence and write it down to a new array. Then, for each value *x* from 1 to *m* we compute the longest segment of the array consisting of element *x* only.

The above operation is performed for 10^{100} seconds. For each integer from 1 to *m* find out the longest segment found at this time.

Input

The first line of the input contains two integers *n* and *m* (1 ≤ *n*, *m* ≤ 100 000) — the number of sequences and the maximum integer that can appear in the sequences.

Then follow *n* lines providing the sequences. Each of them starts with an integer *k*_{i} (1 ≤ *k*_{i} ≤ 40) — the number of integers in the sequence, proceeded by *k*_{i} positive integers — elements of the sequence. It's guaranteed that all integers in each sequence are pairwise distinct and do not exceed *m*.

The total length of all sequences doesn't exceed 200 000.

Output

Print *m* integers, the *i*-th of them should be equal to the length of the longest segment of the array with all its values equal to *i* during the first 10^{100} seconds.
