Live to learn; learn to live
Life is a never ending learning experience...You stop learning at your last breathe...No one really knows what every decision they make will lead to...slow down...breathe in...move on...

Yup... your answer is write but my search code took longer than evil problems that I have seen. The code took a whole of 35 seconds....
$ javac -g *.java; java globalStatics ./input/wt.txt
85...24..72......9..4.........1.7..23.5...9...4...........8..7..17..........36.4.

my code took about 3-4 secs...
Guys, write a better code... it takes no more than 300 ms for my code and that too with lot of informative print commands. I am sure, can be done in about 100 ms.
It does not even have to go thru the bruit force.
25 mins guys!
