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: Accepted)

using System;

namespace ConsoleApp2
{
    class Program
    {
        const string endWord = "END_OF_TEXT";
        static void Main(string[] args)
        {
            string targetWord = Console.ReadLine();
            string[] line;
            bool End = false;
            int count = 0;
            while (!End)
            {
                line = Console.ReadLine().Split();
                for (int i = 0; i < line.Length; i++)
                {
                    if (line[i] == endWord)
                    {
                        End = true;
                        break;
                    }
                    if (line[i].ToUpper() == targetWord|| line[i].ToLower() == targetWord)
                    {
                        count++;
                    }
                }
