Constraints

The length of W ≤ 10

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.

Output

Solution in Ruby (judge verdict: Wrong Answer)

def read_inputs
  word = gets.chomp
  article = []
  loop do
    sentence = gets.chomp
    case sentence
      when "END_OF_TEXT" then break
      else article << sentence
    end
  end
  return word, article
end

word, article = read_inputs
puts article.join(" ").upcase.split(word.upcase).length - 1
