- Suppose you have a stack with a maximum size of 1000 elements and you want to perform the following operations: Push 500 elements onto the stack. Pop 200 elements from the stack. Push 800 elements onto the stack. Pop all remaining elements from the stack. What is the final size of the stack after performing all these operations?The school cafeteria offers circular and square sandwiches at lunch break, referred to by numbers 0 and 1 respectively. All students stand in a queue. Each student either prefers square or circular sandwiches. The number of sandwiches in the cafeteria is equal to the number of students. The sandwiches are placed in a stack. At each step: If the student at the front of the queue prefers the sandwich on the top of the stack, they will take it and leave the queue. Otherwise, they will leave it and go to the queue's end. This continues until none of the queue students want to take the top sandwich and are thus unable to eat. You are given two integer arrays students and sandwiches where sandwiches[i] is the type of the ith sandwich in the stack (i = 0 is the top of the stack) and students[j] is the preference of the jth student in the initial queue (j = 0 is the front of the queue). Return the number of students that are unable to eat. use the following code to complete:-…Give any two characteristics of stacks.
- Queues are often used to simulate situations where people have to wait in line. One scenario we can simulate with a queue is the annual Single’s Night dance at the Elks Lodge. Men and women enter the lodge and stand in line. The dance floor is quite small and there is room for only three couples at a time. As there is room on the dance floor, dance partners are chosen by taking the first man and woman in line. These couples are taken out of the queue and the next set of men and women are moved to the front of the queue. As this action takes place, the program announces the first set of dance partners and who the next people are in line. If there is not a complete couple, the next person in line is announced. If no one is left in line, this fact is displayed.First, let’s look at the data we use for the simulation:F Jennifer IngramM Frank OpitzM Terrill BeckermanM Mike DahlyF Beata LovelaceM Raymond WilliamsF Shirley YawM Don GundolfF Bernica TackettM David DurrM Mike McMillanF Nikki…A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed. Apply an array to a drop-out stack. (Hint: It would make sense to implement a circular array.)A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed.

- Lab 18: Stack, SentenceReverser Java language Use a stack to reverse the words of a sentence. Keep reading words until you have a word that ends in a period, adding them onto a stack. When you have a word with a period, pop the words off and print them. Stop when there are no more words in the input. For example, you should turn the inputMary had a little lamb. Its fleece was white as snow.intoLamb little a had mary. Snow as white was fleece its.Pay attention to capitalization and the placement of the period.Task 07: The concept of Tower of Hanoi discusses a mathematical puzzle where we have three rods and n disks. The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules: 1. Only one disk can be moved at a time. 2. Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack i.e. a disk can only be moved if it is the uppermost disk on a stack. 3. No disk may be placed on top of a smaller disk. Write a program that takes number of disks as input and prints a sequence of steps to solve Tower of Hanoi problem. hint: If number of disks are 3, the program prints following sequence: Move disk I from rod A to rod C Move disk 2 from rod A to rod B Move disk I from rod C to rod B Move disk 3 from rod A to rod C Move disk 1 from rod B to rod A Move disk 2 from rod B to rod C Move disk I from rod A to rod CI'm a programmer, so I drink a lot of coke. To amuse myself, I place the empty cans in a series of stacks, all in a straight line. When I view this series of stacks from the front, I can't always see all the cans, or even all of the stacks, because sometimes a stack can be entirely obscured by a larger stack. When I view the series of stacks from the front, I can infer a minimum number of total cans. I can see each stack that is strictly larger than all the stacks between it and the front of the structure. For each stack I can see, I know how many cans are used to construct that stack. I then total up the number of cans that I know must exist: let's call this number A. I then say I infer A cans in this structure. Let's look at an example. Suppose a series of stacks has the following stack sizes, in order from the front to the back: {1, 4, 3, 4, 6, 6, 2}. I'm able to infer 11 cans from this series: I can see the first, second, and fifth stacks (with 1, 4 and 6 cans respectively). I…
- Create a program that loads the following elements in a stack. (Oppo, Realme, Samsung, Huawei, Vivo). Remove the last element in the stack and display the remaining elements. Show also the size of the stack and find the position of the element ‘Vivo’ in the stack.A common real-life example used to explain stacks is the stack of plates in a cafeteria. Find at least two other real-life examples in which items are added and removed from a container in last-in-first-out order, and use these examples to explain the concept of a stack.Lab 18: Stack, SentenceReverser Use a stack to reverse the words of a sentence.
