Stack implementation with Linked List using Swift
Stack is a linear data structure which follows a particular order in which the operations are performed. The order may be LIFO(Last In First Out) or FILO(First In Last Out). Let's Code : First make a simple Node class , with a data and a pointer: class Node { let nodeVal : Int var next : Node ? init (value : Int ) { self . nodeVal = value } } Now make the Stack Class, As we know Stack follows LIFO. We will implement Push() and Pop() method within the class to Push and Pop elements. class Stack { var top : Node ? func push( _ value: Int ){ let oldTop = top top = Node (value: value) top ?. next = oldTop print ( "Push Item to Stack : \ ( value )" ) } func pop() ->...
