kotlin collection to linked list

To convert a Kotlin collection into a linked list, you can follow these steps:

1. Create an empty linked list: Initialize a variable of type LinkedList, specifying the type of elements it will hold. For example, if you have a collection of integers, you can create a LinkedList().

2. Iterate over the collection: Use a loop or a higher-order function like forEach or map to iterate over each element in the collection.

3. Add each element to the linked list: Within the loop or higher-order function, use the addLast method of the LinkedList to add each element to the end of the linked list. For example, if your linked list variable is called "list", you can add an element by calling list.addLast(element).

4. Complete the iteration: Once you have added all the elements from the collection to the linked list, exit the loop or higher-order function.

5. The linked list is now populated: At this point, the linked list will contain all the elements from the original collection, in the same order.

Here is an example of converting a Kotlin collection into a linked list:

import java.util.LinkedList

fun main() {
    val collection = listOf(1, 2, 3, 4, 5)
    val linkedList = LinkedList<Int>()

    collection.forEach { element ->
        linkedList.addLast(element)
    }

    println(linkedList)
}

In this example, we have a collection of integers (1, 2, 3, 4, 5) and we want to convert it into a linked list. We create an empty LinkedList(), iterate over each element in the collection using forEach, and add each element to the linked list using addLast. Finally, we print the contents of the linked list, which will output [1, 2, 3, 4, 5].
