Problem:
Finding a Word

Write a program which reads a word W and a text T, and prints the number of word W which appears in text T

T consists of string Ti separated by space characters and newlines. Count the number of Ti which equals to W. The word and text are case insensitive.

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

Print the number of W in the text.

Sample Input

who will create and exploit "knowledge" for the new era.
Provides an outstanding computer environment.
END_OF_TEXT

Sample Output

Solution in Ruby (judge verdict: Wrong Answer)

def substrings(str, w)
  length = str.length
  w_length = w.length
  output = []
  for i in 0..(length-1)
    substring = str[i..i+w_length-1]
    output.push(substring)
  end
  return output
end

def count_word(str, w)
  output = substrings(str, w)
  length = output.length
  word_count = 0
  for i in 0..(length-1)
    if output[i] == w
      word_count += 1
    end
  end
  return word_count
end


w = gets.chomp
t_array = []
loop do
  t = gets.chomp.split
  if t == ["END_OF_TEXT"]
    break
  end
  t_array.push(t)
  t_array.flatten!
end
t_str = t_array.join()

puts count_word(t_str, w)
