Challenge: 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.

java

Main

copy
123456789101112
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() } } }

Var allt tydligt?

Hur kan vi förbättra det?
