Scala Programming: Rotate one element left of an given array (length 1 or more) of integers
Scala Programming Array Exercise-8 with Solution
Write a Scala program to rotate one element left of an given array (length 1 or more) of integers.
Sample Solution:
Scala Code:
object Scala_Array
{
def rotate_left(arr: Array[Int]): Array[Int] = {
if (arr.length < 1) false
arr.tail :+ arr.head
}
def main(args: Array[String]): Unit =
{
val nums1 = Array(1,2,3,4,5,6,7)
println("Original Array elements:")
// Print all the array elements
for ( x <- nums1 ) {
print(s"${x}, ")
}
println("\nRotate left one element:")
var result_left1 = rotate_left(nums1)
for ( x <- result_left1 ) {
print(s"${x}, ")
}
val nums2 = Array(1,2)
println("\nOriginal Array elements:")
// Print all the array elements
for ( x <- nums2 ) {
print(s"${x}, ")
}
println("\nRotate left one element:")
var result_left2 = rotate_left(nums2)
for ( x <- result_left2 ) {
print(s"${x}, ")
}
val nums3 = Array(100)
println("\nOriginal Array elements:")
// Print all the array elements
for ( x <- nums3 ) {
print(s"${x}, ")
}
println("\nRotate left one element:")
var result_left3 = rotate_left(nums3)
for ( x <- result_left3 ) {
print(s"${x}, ")
}
}
}
Sample Output:
Original Array elements: 1, 2, 3, 4, 5, 6, 7, Rotate left one element: 2, 3, 4, 5, 6, 7, 1, Original Array elements: 1, 2, Rotate left one element: 2, 1, Original Array elements: 100, Rotate left one element: 100,
