I am very new to scala programming , and I'm stuck with this particular task.
So this is my scala code:
object task {
def main(args: Array[String]) = {
val mystring: Array[String] = Array("This\nis\nrandom\ntext\n\n")
val s = mystring.mkString.split("\n")
println("**********")
for(element <- s)
{
println("* " element " *")
}
println("**********")
}
}
and I get something like this:
**********
* This *
* is *
* random *
* text *
**********
but the main goal is to get this:
**********
* This *
* is *
* random *
* text *
**********
Does anyone know how to solve this?

You need to apply a little math.
val mystring = "This\nis\nrandom\ntext\n\n"
val s = mystring.split("\n")
val mxLen = s.map(_.length).max
println("*" * (mxLen 4))
for(element <- s) {
val eLen = element.length
println("* " element " "*(mxLen-eLen) " *")
}
println("*" * (mxLen 4))
