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

END_OF_TEXT

Sample Output

	char T[2000];
	int num=0;
	int i, j;
	int flag;
	char te[] = "END_OF_TEXT\n";

	scanf("%s", w);

	while(1){
		fgets(T, sizeof(T), stdin);
		printf("%s\n", T);
		if(strcmp(T, te) == 0)
