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

Solution in Ruby (judge verdict: Accepted)

w = gets.chomp
i = 0
loop do
    x = gets.chomp.split
    if x[0] == "END_OF_TEXT"
        break
    end
    x.each do |j|
        k = j.downcase
        if k == w
            i += 1
        end
    #y = x.downcase.scan(/\A#{w}\Z/).size
    end
#    y = x.downcase.scan(/\A#{w}\Z/).size
    #i += y
end
puts "#{i}"
