don't print a blank line at the end of the last case, or the judge will give a result of WA instead of PE, which cost me long time to debug.
any other, try the case below if you use a BFS method:

4 7
##....T
##.###.
S..###.
##.....
0 0

the output should be
Case #1
minimum time = 14 sec


hope ...
