You need to copy the lines from one file to another. In the input, you get the names of the original file and of its copy.

Given the following code:

val scanner = Scanner({ 1 })
val inputName = scanner.nextLine()
val outputName = scanner.nextLine()

File(outputName).{ 2 }.{ 3 }
{
    for (line in File(inputName).readLines()) {
        if (line.{ 4 }) {
            it.{ 5 }(line)
        }
        it.newLine()
    }
}

Please match the numbers and the missing parts of the code.
