Suppose that the MinGap method below is added to the Treap class on Blackboard.
public int MinGap ( )
Returns the absolute difference between the two closest numbers in the treap. For example, if the
numbers are {2, 5, 7, 11, 12, 15, 20} then MinGap would returns 1, the absolute difference between 11
and 12.
Requirements
1. Describe in a separate Design Document what additional data is needed and how that data is used to
support an time complexity of O(1) for the MinGap method. Show as well that the methods Add and
Remove can efficiently maintain this data as items are added and removed. (6 marks)
2. Re-implement the methods Add and Remove of the Treap class to maintain the augmented data in
expected O(log n) time. (6 marks)
3. Implement the MinGap method. (4 marks)
4. Test your new method thoroughly. Include your test cases and results in a Test Document. (4 marks)
Suppose that the two Rank methods below are added to the Skip List class on Blackboard.
public int Rank (T item)
Returns the rank of the given item.
public T Rank(int i)
Returns the item with the given rank i.
Requirements
1. Describe in a separate Design Document what additional data is needed and how that data is used to
support an expected time complexity of O(log n) for each of the Rank methods. Show as well that the
methods Insert and Remove can efficiently maintain this data as items are inserted and removed. (7
marks)
2. Re-implement the methods Insert and Remove of the Skip List class to maintain the augmented data in
expected O(log n) time. Using the Contains method, ensure that added items are distinct. (6 marks)
3. Implement the two Rank methods. (8 marks)
4. Test your new methods thoroughly. Include your test cases and results in a Test Document. (4 marks)

Unlike the recursive approach, which involves multiple function calls and stack overhead, the bottom-up version sorts iteratively by merging small subarrays first, reducing recursion depth and improving performance. Task 1. Implement Bottom-Up Iterative MergeSort о Start with single-element subarrays and iteratively merge them into larger sorted sections. Use a loop-based merging process instead of recursion. ○ Implement an efficient in-place merging strategy if possible. 2. Performance Analysis Compare execution time with recursive MergeSort on random, nearly sorted, and reversed datasets. ○ Measure and plot time complexity vs. input size.

- Given a shared data set, we allow multiple readers to read at the same time, and only one single writer can access the shared data at the same time. In the lecture slides, a solution is given. However, the problem is that the write cannot write forever, if there are always at least one reader. How to ensure that the writer can eventually write? Propose your solution by using semaphores and implemented in Python from threading import Thread, Semaphore from time import sleep from sys import stdout class Reader(Thread): def__init__(self, name): self.n=name; Thread.__init__(self) defrun(self): globalnr, nw, dr, dw whileTrue: # ⟨await nw == 0 then nr += 1⟩ e.acquire() ifnw>0: #if nw > 0 or dw > 0 : dr+=1; e.release(); r.acquire() nr+=1 ifdr>0: dr-=1; r.release() else: e.release() # read data stdout.write(self.n+' reading\n') sleep(1) # ⟨nr -= 1⟩ e.acquire() nr-=1 ifnr==0anddw>0: dw-=1 ; w.release() else: e.release() class Writer(Thread): def__init__(self, name):…arrow_forwardAnnée scolaire: 2024/2025 Collège SMARA Devoir à domicile 1 semestre 2 Prof: NILAJ PHYSIQUE CHIMIE Nom et Prénom: Niveau: 3APIC Exercice 1: Durée: 1 heure 1) Donner la définition des termes suivantes?

Start early in the week the program is due so you can ask questions if you get stuck Node.js and Express and Nunjucks Templates We have gotten to the good stuff. There is a program similar to this assignment given as the last example in the lecture notes for the week that discusses node static files. This program will take more time that previous assignments. There are several examples you should study first, particularly the pizza order example program available in the examples programs folder for the week discussing static files. You should study and run the pizza order program before trying this program. The pseudo-company is called Sun or Fun, which offers cheap flights from Louisville to either Miami or Vegas. Here's a video of how it should work. NOTE: You will hear or see references to Handlebars in this video.
