Write a Scala program to find maximum difference between two elements in a given array of integers such that smaller element appears before larger element

object Scala_Array {
  def diff_between_two_elemnts(nums: Array[Int]): Int = {
    var diff_two_elemnts = Integer.MIN_VALUE;
    for (i <- 0 to nums.length - 1) {
      for (j <- i + 1 to nums.length - 1) {
        diff_two_elemnts = Integer.max(diff_two_elemnts, nums(j) - nums(i));
      }
    }
    return diff_two_elemnts;
  }
  def main(args: Array[String]): Unit = {
    val nums = Array(2, 3, 1, 7, 9, 5, 11, 3, 5);
    println("Original array:")
    for (x <- nums) {
      print(s"${x}, ")
    }
    System.out.print(
      s"\nThe maximum difference between two elements of the said array elements: ${diff_between_two_elemnts(nums)}"
    )
  }
}

Sample Output:

Original array:
2, 3, 1, 7, 9, 5, 11, 3, 5, 
The maximum difference between two elements of the said array elements: 10
