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 C (judge verdict: Time Limit Exceeded)

#include<stdio.h>
#include<string.h>
int main(){
	int count=0, i;
	char s[100], p[1000], end[11]="END_OF_TEXT";
	scanf("%s", s);
	while(1){
		scanf("%s", p);
		if(strcmp(p, end) == 0) break;
		if(strstr(s, p) != NULL) count++;
	}
	printf("%d\n", count);
}
