How to convert a matrix of numbers to a string in Scala

Answer 1

val matrix = Array(
  Array(4, 7, 9, 18, 29, 0),
  Array(1, 9, 18, 99, 4, 3),
  Array(9, 17, 89, 2, 7, 5),
  Array(19, 49, 6, 1, 9, 8),
  Array(29, 4, 7, 9, 18, 6)
)

// Convert the matrix to a string
val matrixAsString = matrix.map(_.mkString(", ")).mkString("\n")

println(matrixAsString)



 
/*
run:

4, 7, 9, 18, 29, 0
1, 9, 18, 99, 4, 3
9, 17, 89, 2, 7, 5
