Implement Queue using Linked List

Algorithm:

• For Enqueue Operation
  • Iterate till node.next = null
  • Add new node to node.next
• For Dequeue Operation
  • Remove it from head and
  • Update head pointer i.e. head = head.next

Latest Source Code:
Github: ListQueue.java

Output:

20 10 
Dequeue: 10
20 
Dequeue: 20
