Scala Programming: Check if a given number is present in fast or last position of a given array of length 1 or more

Scala Programming Array Exercise-2 with Solution

Write a Scala program to check if a given number is present in fast or last position of a given array of length 1 or more.

Sample Solution:

Scala Code:

object Scala_Array {
   def test(x:Int, nums: Array[Int]) : Boolean = {
    if (nums.length < 1) false 
     else nums.head == x || nums.last == x
    }     
   def main(args: Array[String]): Unit = { 
     println("Check if a given number is present in fast or last position in an array!")
     var nums1 = Array(1,2,3,4,5,6)
     var n1 = 5;
     println(s"Given number: ${n1}")
     println("Original Array elements:")
     // Print all the array elements
      for ( x <- nums1 ) {
         print(s"${x}, ")        
       }
      println("\nResult: "+test(n1, nums1))
     var nums2 = Array(1,2,3,4,5,1)
     var n2= 1;
     println(s"Given number: ${n2}")
     println("Original Array elements:")
     // Print all the array elements
      for ( x <- nums2 ) {
         print(s"${x}, ")        
       }
      println("\nResult: "+test(n2, nums2))
   }
}

Sample Output:

Check if a given number is present in fast or last position in an array!
Given number: 5
Original Array elements:
1, 2, 3, 4, 5, 6, 
Result: false
Given number: 1
Original Array elements:
1, 2, 3, 4, 5, 1, 
Result: true
