multiple choice:
consider an array based implementation of a stack and its push operation. Beginning with an array of length 1 = (2^0), consider where the array’s length will be doubled whenever an insertion(via the push operation) is attempted when the array is full. What is the amortized complexity of performing a sequence of n push operations.
a) Θ(log n)
b) Θ(n)
c) Θ(n^2)
d) Θ(1)
For starting array 25 22 24 28 26 29 21 23 27, tell, for each element: what is the
FIRST other element that it gets compared to during the sort? Assume, that when a
node is potentially moving down, that it gets compared to its left child first. (The first
line below asks you to tell me what the number 21 is compared to, the first time that
it is compared to anything within the heap sort algorithm. The second line asks what
22 is compared to for its first comparison, etc.)

THE ANSWER
After the heap is built, and the first element deleted, value 22 takes its place, what
are the next two comparisons that happen? The first is between 22 and
24
The next is between that value and 26
What are they? The starting array is still 25 22 24 28 26 29 21 23 27. (Just enter

# Problem 2# Implement a hashtable using an array. Your implementation should include public methods for insertion, deletion, and# search, as well as helper methods for resizing. The hash table is resized when the max chain length becomes greater# than 3 during insertion of a new item. You will be using linear chaining technique for collision resolution. Assume# the key to be an integer and use the hash function h(k) = k mod m where m is the size of the hashtable. You can use# python list methods in your implementation of the chain or you can also use your linked list implementation from# coding assignment 2, problem 1. You can make necessary changes to __hashtable initialization in the __init__ method# if you are using your linked list implementation. The provided code uses python lists for the __hashtable variable.

- 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. 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). Part 1: Modify the code given and make it more efficient. You can try to implement your own stack or your own Queue. Or you can use the sandwiches array as a stack without making a separate Stack class. Same with the students array. Part 2: After modifying the code, explain how it works, and why it is more efficient than the solution that you started with.

There is a story about Buddhist monks who are playing this puzzle with 64 stone disks. The story claims that when the monks finish moving the disks from one post to a second via the third post, time will end. Eschatology (concerns about the end of time) and theology will be left to those better qualified; our interest is limited to the recur- sive solution to the problem. A stack of n disks of decreasing size is placed on one of three posts. The task is to move the disks one at a time from the first post to the second. To do this, any disk can be moved from any post to any other post, subject to the rule that you can never place a larger disk over a smaller disk. The (spare) third post is provided to make the solution possible. Your task is using c++ write a recursive function that describes instructions for a solution to this problem. We don’t have graphics available, so you should output a sequence of instructions that will solve the problem. Hint: If you could…arrow_forward
