1)Given a Stack implemented with a Linked List, and an O(1) implementation of push and pop,show the Linked List after the following commands are executed: Stack myStack = new Stack(); myStack.push(20); myStack.push(40); myStack.pop(); myStack.push(60); myStack.push(80); 2)If the same commands were used but the Stack was implemented with an Array with maximum size of 10, show what the array would look like after all these commands are executed. Assume O(1) implementation of push and pop here as well. 3)Given a Queue...

Using java Create a simple queue class and a simple stack class. The queue and stack should be implemented as a linked list. Create three functions that utilize these data structures Write a function that opens a text file and reads its contents into a stack of characters. The program should then pop the characters from the stack and save them in a second text file. The order of the characters saved in the second file should be the reverse...

Infix Expression Evaluator For this project, write a C program that will evaluate an infix expression. The algorithm REQUIRED for this program will use two stacks, an operator stack and a value stack. Both stacks MUST be implemented using a linked list. For this program, you are to write functions for the linked list stacks with the following names: int isEmpty (stack); void push (stack, data); data top (stack); void pop (stack); // return TRUE if the stack has no...

Lab 3 – Array-Based Stack and Queue Overview In this assignment, you will be implementing your own Array-Based Stack (ABS) and Array-Based Queue (ABQ). A stack is a linear data structure which follows the Last-In, First-Out (LIFO) property. LIFO means that the data most recently added is the first data to be removed. (Imagine a stack of books, or a stack of papers on a desk—the first one to be removed is the last one placed on top.) A queue...
