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.

Solution in Scala (judge verdict: Wrong Answer)

import scala.io.Source

object Main extends App {
  val src = Source.stdin.getLines.toList.flatMap(_.split(" ").map(_.toLowerCase).toList)
  val target = src(0)

  def removeOthers(src: List[String]): List[String] = {
    for {
      word <- src.tail
      if (word.contains(target))
    } yield word
  }

  println(removeOthers(src).length)
}
