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.

Example

END_OF_TEXT


Output

3
one_word = raw_input()
word_count = 0
word_list = []

while 1:
	temp = raw_input()
	word_list += temp.split()
	
	if word_list[len(word_list)-1] == "END_OF_TEXT":
		break

for word in word_list:
	if one_word.lower() == word.lower():
		word_count += 1

print word_count
