The Nlogonian Aquatic Surf Championship, to be hosted in Bonita Horeleninha (BH) city, is about to start! The game CheeseBreadSweeper is very popular in this town!

The game board consists on a matrix with N rows and M columns. Each cell contains a Cheese Bread or the number of Cheese Breads present in its adjacent cells. A cell is adjacent to another if it is immediately on the left, the right, above or bellow the cell. Please notice that, if a cell does not contain a Bread Cheese, then it must have a number from 0 to 4, inclusive.

Given the positions of the Cheese Breads, determine the game board!


The input contains several test cases. The first line of each test case contains integers N and M (1 ≤ N, M ≤ 100). Next N lines contains M integers each, separated by spaces, describing the Cheese Breads on the board. The j-th integer in the i-th line is 1 if there is a Cheese Bread at row i and column j of the board, or 0 otherwise.

The input ends with end-of-file (EOF).


For each test case, print N lines with M integers each, not separated by spaces, describing the board’s configuration. If a cell contains a Cheese Bread, print 9 for it; otherwise, print the number the cell must contain.
