Scala function: Check if a list is sorted
Scala Function Exercise-10 with Solution
Write a Scala function to check if a given list is sorted in ascending order.
Sample Solution:
Scala Code:
object ListSortChecker {
def isSortedAscending[A](list: List[A])(implicit ord: Ordering[A]): Boolean = {
list.sliding(2).forall { case List(a, b) => ord.lteq(a, b) }
}
def main(args: Array[String]): Unit = {
val list1 = List(1, 2, 3, 4, 5, 6)
val list2 = List(4, 2, 5, 1, 6, 3)
println("List1: "+list1)
println(s"Is List1 is sorted in ascending order? ${isSortedAscending(list1)}")
println("List2: "+list2)
println(s"Is List2 is sorted in ascending order? ${isSortedAscending(list2)}")
}
}
Sample Output:
List1: List(1, 2, 3, 4, 5, 6) Is List1 is sorted in ascending order? true List2: List(4, 2, 5, 1, 6, 3) Is List2 is sorted in ascending order? false
