bookChallenge: Fill a 2D Array

Task

Your task create a 3x2 2D array of integers named matrix and fill it with elements which have the value of equal to i + j, where i is the row index, and j is the column index. Use two for loops with the loop variables named i and j to iterate over its indices.

object Main {
  def main(args: Array[String]): Unit = {
    var ___ = Array.___[___](___, ___)  // Create a 3x2 2D array
    for (___ ___ matrix.___) {  // Iterate over the row indices
      for (___ ___ matrix(___).___) {  // Iterate over the columns indices
        matrix(___)(___) = ___  // Assign the sum of indices to the current element
        print(matrix(___)(___) + " ")
      }
      println()
    }
  }
