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.
