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: Wrong Answer)

using System;

namespace Ssearch
{
    class Program
    {
        static void Main(string[] args)
        {
            string word = Console.ReadLine();
            int f = 0;
            while(true)
            {
                string s = Console.ReadLine();
                if (s == "END_OF_TEXT")
                {
                    break;
                }
                int foundIndex = s.IndexOf(word, StringComparison.OrdinalIgnoreCase);
                while (foundIndex >= 0)
                {

                    ++f;
                    //?¬????????´¢????§???????
                    int nextIndex = foundIndex + word.Length;
                    if (nextIndex < s.Length)
                    {
                        //?¬???????????????¢???
                        foundIndex = s.IndexOf(word, nextIndex, StringComparison.OrdinalIgnoreCase);
                    }
                    else
                    {
                        //???????????§????´¢????????¨???????????????
                        break;
