Use print() instead of puts() and insert \n characters as needed.

change last line:

loc.puts((i+65).chr+' '+a[i].to_s) if a[i]>0

Alternatively, continue to use puts() and use string variable
interpolation instead of separate parameters. In other words:

loc.puts("#{(i+65).chr} #{a[i]}") if a[i]>0

Thank you so much! That kinda sucks when you need to output an int,
you need to remember the to_s
Thank you again

You don't. Just use the interpolation technique that was suggested
with either puts() or print().

Hope that helps.
