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.

Solution in Ruby (judge verdict: Runtime Error)

searchStr = gets.chomp.downcase;
 
count = 0;
 
while true do
 
	targetStr = gets;
 
	if targetStr == "END_OF_TEXT" then
		break;
	end
 
	targetStr = targetStr.downcase;
 
	aryTargetStr = targetStr.split(' ');
 
	for i in 0..aryTargetStr.length-1 do
 
		if aryTargetStr[i] == searchStr then
			count = count + 1;
 		end
	end
 
end
 
puts count.to_s;
