Scala Programming: Find the maximum and minimum value of an array of integers

Scala Programming Array Exercise-9 with Solution

Write a Scala program to find the maximum and minimum value of an array of integers.

Sample Solution:

Scala Code:

object Scala_Array {

 def min_max(a: Array[Int]) : (Int, Int) = {
     if (a.isEmpty) throw new IllegalArgumentException("Blank Array...!")
    a.foldLeft((a(0), a(0)))
    { case ((min, max), e) => (math.min(min, e), math.max(max, e))}
     }
  
     
   def main(args: Array[String]): Unit = {
        val nums1 = Array(1, 2, 3, 4, 5, 7, 9, 11, 14, 12, 16)        
        println("Original Array elements:")
        // Print all the array elements
        for ( x <- nums1 ) {
         print(s"${x}, ")        
          }
        println("\nMaximum - Minimum value of the said array: " +min_max(nums1));
        val nums2 = Array(-111,-124)        
        println("Original Array elements:")
        // Print all the array elements
        for ( x <- nums2 ) {
         print(s"${x}, ")        
          }
        println("\nMaximum - Minimum value of the said array: " +min_max(nums2));
        
        val nums3 = Array(10)        
        println("Original Array elements:")
        // Print all the array elements
        for ( x <- nums3 ) {
         print(s"${x}, ")        
          }
        println("\nMaximum - Minimum value of the said array: " +min_max(nums3));
        var nums4 : Array[Int] = Array()
        println("Result: " +min_max(nums4));
         
      } 
 } 

Sample Output:

Original Array elements:
1, 2, 3, 4, 5, 7, 9, 11, 14, 12, 16, 
Maximum - Minimum value of the said array: (1,16)
Original Array elements:
-111, -124, 
Maximum - Minimum value of the said array: (-124,-111)
Original Array elements:
10, 
Maximum - Minimum value of the said array: (10,10)

Previous: Write a Scala program to rotate one element left of an given array (length 1 or more) of integers.
Next: Write a Scala program to calculate the sum of the last 3 elements of an array of integers. If the array length is less than 3 then return the sum of the array. Return 0 if the array is empty.
