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 JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main {
	public static void main(String[] args) throws Exception {
		Scanner sc = new Scanner(System.in);
		
		String W = sc.nextLine();
		String T = "";
		String line = sc.nextLine();
		while (!"END_OF_TEXT".equals(line)) {
			T += line;
			line = sc.nextLine();
		}
		int cnt = 0;
		for (;;) {
			int index = T.indexOf(W);
			if (index == -1) break;
			cnt++;
			if (index+1 >= T.length()) break;
			T = T.substring(index+1);
		}
		System.out.println(cnt);
	}
