W consists of lower case letters

The length of T in a line ≤ 1000

Input

In the first line, the word W is given. In the following lines, the text T is given separated by space characters and newlines.

"END_OF_TEXT" indicates the end of the text.

Solution in Ruby (judge verdict: Accepted)

def main
  fh=STDIN
  #fh=File.new("x.txt", "r")
  w=fh.gets.chomp.downcase
  t=fh.read.downcase
  t.sub!(/END_OF_TEXT.*/,"")

  puts t.split.count{|x|x==w}
end

if $0 == __FILE__ then
  main
end
