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

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 Kotlin (judge verdict: Accepted)

const val EOF = "END_OF_TEXT"

fun main(args: Array<String>) {
    val target = readLine() ?: return
    var count = 0
    while (true) {
        val texts = readLine()?.split(" ")?.map { if(!it.equals(EOF))it.toLowerCase() else it } ?: break
        texts.forEach{
            if(it == target) count++
        }
        if(texts.contains(EOF)) break
    }
    println(count)
}
