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;

	public class Class1
	{
		public static void Main()
		{   string question=Console.ReadLine();
		
			int counter=0;
			int foundIndex=0;
			string target=Console.ReadLine();
		    while(target!="END_OF_TEXT")
		    {
				
		    	int nextIndex=0;
		    do{
		    foundIndex=target.IndexOf(question,nextIndex,StringComparison.OrdinalIgnoreCase);
		    if(foundIndex!=-1)
		    {
		    	counter++;
		    	nextIndex=foundIndex+question.Length;
		    
		    }
		    else if(foundIndex==-1)
		    {
		    	break;
		    }
		    	}while((nextIndex+question.Length-1)<target.Length);
		    	target=Console.ReadLine();
				
			}
		    Console.WriteLine(counter);
		    
		}
		
	}
