Use an array and two index variables. Write functions or methods push, pop, and sizeof. Then write a main function or method that will allocate the stack at n=10 and push some strings in ii, print out the size, and then pop some strings from it. Note make stack be be able to hold string variable type. java
Find out what happens when you just leave the stack alone.
Create your own called class called Stack Your class should store items transparently. You should add items using a Push method and remove them through the Pop method. Add an IsEmpty method should return whether there are any items in the stack or not. A CountItems method should tell you the current number of items in the stack Write some code to test your Stack class using the shapes in part 1.
stacks and queues. program must be able to handle all test cases without causing an exception Note that this problem does not require recursion to solve (though you can use that if you wish).

I have implemented a stack using arrays. The array is 5 elements long and is called examstack. The contents are: examstack[0] = 36 examstack[1] = 49 examstack[2] = 7 examstack[3] = 67 examstack[4] = 9 If I did a Pop what would be returned? 9 or 36 09 07 O 67 O 9 or 67 36 or 49 O 36 49
What is the operation that adds items to a stack? Get Set Pop Push
OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly without any errors and provide the code with the screenshots of the outputs. The code must have a function that takes a pair of strings (tuple) and returns a unit. Make sure to have the following methods below: -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit: onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the top two values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction where if top two elements in the stack are integer numbers, pop the top element(y) and the next element(x), subtract y from x, and push the result x-y back onto the stack…
# viewGame(G, i) takes a game description G (a dictionary of the type# produced by newGame()) and an integer player index i and returns a# string that, when printed, describes the state of the game from# player i's perspective.## Example:# >>> viewGame(G, 1)# '\nPlayer2 to play (score=0):\n 1[ ] 2[ ] 3[ ]'## Note the spacing and explicit newlines, and the fact that the player# numbers use 1-based indexing even though internally the game data# structures use Pythonic 0-based indexing.
You will create two programs. The first one will use the data structure Stack and the other program will use the data structure Queue. Keep in mind that you should already know from your video and free textbook that Java uses a LinkedList integration for Queue. Stack Program Create a deck of cards using an array (Array size 15). Each card is an object. So you will have to create a Card class that has a value (1 - 10, Jack, Queen, King, Ace) and suit (clubs, diamonds, heart, spade). You will create a stack and randomly pick a card from the deck to put be pushed onto the stack. You will repeat this 5 times. Then you will take cards off the top of the stack (pop) and reveal the values of the cards in the output. As a challenge, you may have the user guess the value and suit of the card at the bottom of the stack. Queue Program There is a new concert coming to town. This concert is popular and has a long line. The line uses the data structure Queue. The people in the line are objects…
] ] get_nhbr In the cell below, you are to write a function called "get_nhbr(Ist, graph)" that takes in two inputs: a list of vertices and a graph. The function is to return a list that contains the neighborhood of the vertices in 'Ist' (remember that this means you are finding the union of the individual vertices' neighborhoods). + Code + Markdown After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (get_nhbr(["A", "D"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]}), get_nhbr(["B", "C", "F"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]})) This should return ["B"] ["A", "D", "E"] Python Python
