Scala Programming: Calculate the length of a given list
Scala Programming List Exercise-24 with Solution
Write a Scala program to calculate the length of a given list.
Sample Solution:
Scala Code:
object Scala_List {
def length[A](nums:List[A]):Int = {
nums.length
}
def main(args: Array[String]): Unit = {
val nums1 = List(1,2,3,4)
println("Original List:")
println(nums1)
println("Length of the said list:")
println(length(nums1))
val nums2 = List(1, List(2, 3, 4), List(List(List(5, 6, 7))), List(8, 9), List(10), 11)
println("Original List:")
println(nums2)
println("Length of the said list:")
println(length(nums2))
val colors = List("Red", "Green", "Black", "Pink", "Orange", "White","Yellow")
println("Original List:")
println(colors)
println("Length of the said list:")
println(length(colors))
}
}
Sample Output:
Original List: List(1, 2, 3, 4) Length of the said list: 4 Original List: List(1, List(2, 3, 4), List(List(List(5, 6, 7))), List(8, 9), List(10), 11) Length of the said list: 6 Original List: List(Red, Green, Black, Pink, Orange, White, Yellow) Length of the said list: 7
