Challenge: Fill an Array

Task

Your task is to create an array of integers of size 20 named testArray and fill it with numbers from 1 to 20 inclusive using a for loop with the loop variable named i to iterate over its indices in a concise way.

java

Main

copy

              
12345678

            
object Main {
  def main(args: Array[String]): Unit = {
    var ___ = new ___[___](___)  // Declare an array variable
    for (___ ___ testArray.___) {
      ___(___) = ___  // Fill the array
    }
  }
}

Tutto è chiaro?
