Description
Given a N x N board and a coordinate of point S, (x, y), you need to compute the shortest distance between each grid on the board and the point S.
The shortest distance only counts horizontal and vertical steps. The distance between one grid and the neighbor one is 1.

Input
Each testcase has two lines. The first line has N(3<=N<=7), which means the size of the board. The total number of grids on the board would be N x N.
The second line has two numbers, x and y(1<=x, y<=N), which mean the coordinate of the point S. x is the row index, and y is column index.
Note that (1, 1) is on the most top-left of the board.
Output
Print out the board, where the element of each grid is the shortest distance from the point S.
The element of point S is 0.
Note that you have to use "%3d" to print the output, and there is a ' \n ' at the last line.
