# TASK #2 > Minesweeper Game
# Submitted by: Cheok-Yin Fung
# You are given a rectangle with points marked with either x or *. Please
# consider the x as a land mine.
#
# Write a script to print a rectangle with numbers and x as in the Minesweeper
# game.
#
# A number in a square of the minesweeper game indicates the number of mines
# within the neighbouring squares (usually 8), also implies that there are no
# bombs on that square.
#
# Example
# Input:
#     x * * * x * x x x x
#     * * * * * * * * * x
#     * * * * x * x * x *
#     * * * x x * * * * *
#     x * * * x * * * * x
#
# Output:
#     x 1 0 1 x 2 x x x x
#     1 1 0 2 2 4 3 5 5 x
#     0 0 1 3 x 3 x 2 x 2
#     1 1 1 x x 4 1 2 2 2
#     x 1 1 3 x 2 0 0 1 x
