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.
Input
6 3 0 1 0 6 8 5 4 2 9 0 1 5 5 9 5 0 9 1 5 4 0 1 0 0 2 3 0 0 4 5 0 0 6 7 0 0 8 9 5 5 1 5 0 2 4 6 8 3 1 7 8 9
Output
