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)

search_word = STDIN.gets.chomp.downcase
count = 0
eof = false

until eof do
	text = STDIN.gets.chomp.split(" ")
	text.each {|test_word|
		if test_word.eql?("END_OF_TEXT") && text.length == 1 then
			eof = true
			break
		end
		test_word.downcase!
		count += 1 if test_word.eql?(search_word)
	}
#	print count,", ",text,"\n"
end

print count, "\n"
