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.

using System;

namespace ITP1_9_A {
    class Program {
        static void Main(string[] args) {
            string s = Console.ReadLine();
            int count = 0;
            while(true) {
                string str = Console.ReadLine();
                if(str == "END_OF_TEXT") break;
                string Lowstr = str.ToLower();
                string[] strArray = Lowstr.Split(' ');
                for(int i = 0; i < strArray.Length; i++) {
                    if(strArray[i] == s) count++;
                }
            }
            Console.WriteLine(count);
