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.

Solution in Ruby (judge verdict: Wrong Answer)

word = gets.chomp.downcase
len = word.size
j = 0

while true
  t = gets.chomp
  break if t=="END_OF_TEXT"  
  t.downcase!
  
  for i in 0..t.size-1
    if t[i]==word[0]
      for k in 1..len
        break if t[i+k]!=word[k]
        j+=1 if k==len
      end
    end
  end
end

puts j
