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
