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

who will create and exploit "knowledge" for the new era.
Provides an outstanding computer environment.
END_OF_TEXT

Sample Output

Solution in Scala (judge verdict: Wrong Answer)

import scala.io.StdIn

object Main extends App {

  private val w = StdIn.readLine()
  val wsize = w.length
  var text = ""
  var cnt = 0
  

  def loop(index: Int, target: String): Unit = {
    if(index >= 0){
      val next = target.indexOf(w,index)
      if(next >= 0) {
        cnt +=1
        loop(next+wsize, target)
      }
    }
  }

  do {
    loop(0, text.toLowerCase)
    text = StdIn.readLine()
  } while(text != "END_OF_TEXT")
  
  println(cnt)
  
}
