Frequencies on a board

We have a board with $m$ rows and $n$ columns. In each board cell there is a digit (0, ..., 9). Write a program that computes the frequency of each digit in each of the $n$ columns of the board. The number of rows of a board can be very large.

Input

The input is a series of cases. Each case consists of two integers greater than zero $m$ and $n$ denoting, respectively, the number of rows and columns on the board, followed by a row-by-row description of the board’s digits.

Output

For each case in the input, a frequency table. The table has ten rows, respectively representing the digits 0, .., 9 and $n$ columns. The table value in row $d$ column $j$ should be the frequency of digit $d$ in column $j$ of the corresponding input board. A blank line appears after the frequency table.
