hi all,



i have a string need to replace every 10th blank space of the string
with some special character.is it possible, the string does not have any
"\n", one single line.

blank space of the string with some special character.is it possible,
the string does not have any "\n", one single line." need to
place @ in
place of every 10 blank space.

string = "i have a string need to replace every 10th
blank space of the string with some special character.is it possible,
the string does not have any \"\\n\", one single line."

i=0
string.each_byte { |c|
  i+=1
  string[i] = ''*'' if i%10 == 0
}

puts string

What have you tried in order to achieve this?
You may not end up with the most elegant solution yourself but surely any
programmer can work out some way of achieving this.
Post your efforts and there may be some help.
