Arundel is writing a quick lookup system for the SuperMall's touchscreen directory which helps shoppers locate stores within the mall. The stores in the mall very rarely change because every store has a long-term lease, so there will seldom be changes in the data. Arundel is deciding whether to use a sorted linked list, a binary search tree or a hash table. Based on the information from this course, which data structure should he choose? Briefly explain.

Which data structure should Arundel choose and why?
Step by step
Solved in 2 steps
- in c++ vs19: Go on https://www.imdb.com/ and look up for some movies. Select at least 10 movies. For each movie you choose, store its title into an array called movies and its rate (score) into a second array called ratings. The same information for a single movie must be stored in elements having the same index in the two arrays. For example, if Jurassic Park is the third movie you choose, then both its title and its rate should have index 2.movies[2] = "Jurassic Park";rating[2] = 8.1;Once you filled your arrays, print the list of all the movies from the highest score to the lowest. Follow this format:number_in_ranking. movie_title (movie_rate) newlineIf two movies have the same rate, their order doesn’t matter.Note: You cannot use structs, you cannot use classes, you cannot use matrices, you cannot use advanced data structures, you cannot use std::swap.Note: You can use templates if you need to.Remember to comment the code such that it is easy for other developers to understand…Select true or false for the statements below.

Explain your answers if you like to receive partial credit Which of the following is true about searching elements in an unordered array? With the data is unsorted, search is O(n) because if the element you are looking for is not there, you have to check every element in the array If you start at the end of the array and traverse to index 0, search improves to O(log n) because you only have to look at half of the array If you get lucky with checking the first element and find it immediately, then the worst case performance of search improves to O(n^2) Which of the following is true about searching elements in an ordered array? You cannot use binary search on an ordered array so the performance is O(n) If there are no holes in the array and the elements are all next to each other, then the performance for search improves to…Select true or false for the statements below.

Create a variable registrationList that will hold strings. It should be empty after initialization. Your friend Sara is the first to register for the event. Add her name to registrationList using the append(_:) method. Print the contents of the collection. Add four additional names into the array using the += operator. All of the names should be added in one step. Print the contents of the collection. Use the insert(_:at:) method to add Charlie into the array as the second element. Print the contents of the collection. Somebody had a conflict and decided to transfer registration to someone else. Use array subscripting to change the sixth element to Rebecca. Print the contents of the collection. Call removeLast() on registrationList. If done correctly, this should remove Rebecca from the…Question No. 3: Create a Numpy List named as marks with six float numbers, showing the final marks of a student in six subjects. Round the marks from marks array from Q-3 a) upto two decimal numbers What if you need to create the same list as Q-3 a), but for five students. Can you still use 1-D array? How many dimensions should be there? Find the highest marks a student has obtained using marks array from Q-3 a) Use seaborn to show marks array from Q-3 a)
- Using Java & Apache NetBeans Provide screenshots of the OUTPUT! Create a two-dimensional array of type double to contain the three different SD Marks (JD521, PRG521, and IP521) for six different students. A single array of type String must be used to store the student names (Maxwell, Carl, Gerhard, Paul, James, and Cena). Allow a user to enter in a number, ranging from 1 to 6, which will represent the student position in the table MCSD max and present the marks for each respecting module. The program can only stop when the user enter a number greater than 6. Printout the student name including the JD521, PRG521, and IP521 max, the total of marks and the average of all marks. Use a condition statement to decide that the student has passed or not (Pass rate is 70).def create_identity_matrix(n):"""Create a nxn sized identity matrix.

Create a function that filters out negative numbers In this challenge, you'll have a function that takes an array as an input and returns an array. But if all goes according to plan, it'll remove the negative numbers. This is another example of a task that'll be useful when combing through data and looking for clever ways to eliminate "bad data."
