Text processing/Max licenses in use: Difference between revisions

=={{header|Kotlin}}==

The link for downloading the file, mlijobs.txt, is currently broken so I've created a small file myself to test the program:

<lang scala>// version 1.1.51

import java.io.File

fun main(args: Array<String>) {

val filePath = "mlijobs.txt"

var licenses = 0

var maxLicenses = 0

val dates = mutableListOf<String>()

var f = File(filePath)

f.forEachLine { line ->

if (line.startsWith("License OUT")) {

licenses++

if (licenses > maxLicenses) {

maxLicenses = licenses

dates.clear()

dates.add(line.substring(14, 33))

}

else if(licenses == maxLicenses) {

dates.add(line.substring(14, 33))

}

}

else if (line.startsWith("License IN")) {

licenses--

}

}

println("Maximum simultaneous license use is $maxLicenses at the following time(s):")

println(dates.map { " $it" }.joinToString("\n"))

}</lang>

The file used for testing:

<pre>
