Hackerrank Not accept golang solution

hey , im new with golang i was trying to solve this hacker rank question but the site doesnt seem to properly support the language
my algorithm and output seems to be right (edited)
It would be great if someone could tell me y its not accepting the output

link to the problem : https://www.hackerrank.com/challenges/bomber-man/problem

here my solution : https://play.golang.org/p/yLw93v3kqL6

also any review on the way im writing in go would also be helpful

Thank you

It looks as if they expect the letter O where you print the digit 0.

I can’t access the challenge though… I do get a 404.


i feel so stupid right now xD but Thank you for taking the time, either way 3/4 my test cases failed due to timeout
