Instructions

Your task is to add flower counts to empty squares in a completed Flower Field garden. The garden itself is a rectangle board composed of squares that are either empty (' ') or a flower ('*').

For each empty square, count the number of flowers adjacent to it (horizontally, vertically, diagonally). If the empty square has no adjacent flowers, leave it empty. Otherwise replace it with the count of adjacent flowers.

For example, you may receive a 5 x 4 board like this (empty spaces are represented here with the '·' character for display on screen):

·*·*·
··*··
··*··
·····

Which your code should transform into this:

1*3*1
13*31
·2*2·
·111·
