Create a doubly linked list in Go using the container/list package to efficiently add, remove, and iterate over elements.
Use the container/list package to create a doubly linked list by calling list.New() and manipulating elements with methods like PushBack, Front, and Next.
package main
import (
"container/list"
"fmt"
)
func main() {
l := list.New()
l.PushBack(1)
l.PushBack(2)
l.PushBack(3)
for e := l.Front(); e != nil; e = e.Next() {
fmt.Println(e.Value)
}
}
A doubly linked list is a data structure where each item holds a reference to both the next and previous items, allowing you to move forward or backward through the data. Think of it like a train where each car is connected to the one in front and the one behind, making it easy to insert or remove cars anywhere in the line without rearranging the whole train. You use this when you need to frequently add or remove items from the middle of a sequence.
