Doubly Linked List in Go

package main

/**
 * Project 3: programming in Go lang
 * Using Go Lang, write a program that:
 *    - fills an array with random integers in the range 10 to 99.
 *    - builds a Doubly LinkedList by inserting the integers in the array into the data structure.
 *    - finds the length of a given LinkedList.
 *    - finds the minimum value in a given LinkedList.
