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.StdIn

object Main extends App {
  val pattern = StdIn.readLine().toString.map(_.toLower)
  var text = ""
  var line = ""
  while (line != "END_OF_TEXT") {
    line = StdIn.readLine().toString
    text += line
  }
  val matchCount = pattern.r.findAllIn(text.map(_.toLower)).matchData.map(_.start).toList.length
  println(matchCount)
}
