    Scala solution

    def diagonalDifference(arr: Array[Array[Int]]): Int = {
    // Write your code here
    val n = arr.length
    var primaryDiagonal = 0
    var secondaryDiagonal = 0

    for (i <- 0 until n) {
        primaryDiagonal += arr(i)(i)
        secondaryDiagonal += arr(i)(n - i - 1)
    }

    Math.abs(primaryDiagonal - secondaryDiagonal)

    }
