Scala Programming: Add each element n times to a given list of integers

Last update on June 12 2025 12:57:28 (UTC/GMT +8 hours)

Write a Scala program to add each element n times to a given list of integers.

Sample Solution:

Scala Code:

object Scala_List { def n_times_elements[A](o_list:List[A], n: Int):List[A] = { o_list flatMap { element => List.fill(n)(element) } } def main(args: Array[String]): Unit = { val nums = List(1,2,3,3,4,5,6,7) println("Original List:") println(nums) val result = n_times_elements(nums, 3) println("Add each element 3 times to a given list of integers:") println(result) } }

Sample Output:

Original List: List(1, 2, 3, 3, 4, 5, 6, 7) Add each element 3 times to a given list of integers: List(1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7)
