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.

Sample Input

object Main {

  def main(args: Array[String]): Unit = {

    val w = StdIn.readLine()

    var count = 0
    while(true){
      val line = StdIn.readLine()
      if(line == "END_OF_TEXT"){
        println(count)
        return
      }
      for(word <- line.toLowerCase.split(" ")){
        if(w == word){count += 1}
      }
    }
