In Scala, this is how I sum the Int values of a multidimensional array:

val data = Array.ofDim[Int](200, 200, 200)
// fill data with Int values

val sum = data.map(i => i.map(j => j.sum).sum).sum

Is there a shorter, perhaps easier to read, way of getting the sum of the array?

    Consider asking on Code Review. That aside, consider a function for flattening the array. Commented Mar 6, 2019 at 17:07

A good solution would be:

val sum = data.flatten.flatten.sum
