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.

#include <bits/stdc++.h>
using namespace std;
int main(void){
	string  y;
	int a = 0;
	cin>>y;
	string  x;
	while(true){
		cin>>x;
		for(int i = 0;i<x.size();i++){
		x.at(i) = (char)tolower(x.at(i));
		}
		if(x == "END_OF_TEXT")break;
		if(x == y)a++;

	}
	cout<<a<<endl;
	return 0;
