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

Solution in Scala (judge verdict: Wrong Answer)

import scala.io.Source

object Main{
  def main(args: Array[String]){
    val line =
      for{
        in <-Source.stdin.getLines.toList
      } yield in

    def countNumOfStr(s:String, w:String):Int ={
      if(s.contains(w) == false) 0
      else if(s.contains(w) == true) 1 + countNumOfStr(s.drop(s.indexOfSlice(w) + w.length), w)
      else 0
    }
    println(countNumOfStr(line.tail.mkString(" "), line(0)))
  }
}
