The formal approach to determining the big-O complexity of an algorithm is to set up recurrence relations and solve them. The recurrence relation for the Linear Search algorithm is defined by: I. T(n)=T(n-1)+1 II. T(n) = 2T(n/2)+1 II. T(n)=T(n-1)+Theta(n) IV. T(n)=2T(n/2)+Theta(n) V. None of the above Ov OII
Given an array that represents Breadth First Search or BFS traversal of a Complete Binary Search Tree, implement a recursive void method to print the preOrder traversal of the same Complete Binary Search Tree. You do not need to construct the BST. A Complete Binary Search Tree is a BST in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible. Following is an example of a Complete Binary Search Tree: A. BFS traversal array (level by level from left to right): bfs[] = {50, 35, 55, 30, 45} B. PreOrder traversal (middle, left, right) : 50 35 30 45 55 Your recursive method "void convertBFStoPreOrder" will get an array A as an input and will print B. Hints: In the given BFS traversal array, bfs[], if i is the index of a parent, 2i+1 will give you the index of the left child, and 2i+2 will give you the index of the right child. "Assume that input array is always correct and represent a correct BFS traversal of a Complete BST."…
Computer Science please solve this problem as soon as possible Write a function to insert the element into the linked list the given number X. E.g., for a given set of integers, [2, 4, 12, 6, 5, 3], the linked list is 2->4->12->6->5->3. For a given number, (X=15), the count will be 11 that are (2,4), (2,12), (2,6), (2,5), (2,3), (4,6), (4,5), (4,3), (6,5), (6,3), (5,3).
How to implement Floyd algorithm and Dijkstra algorithm. These two algorithms must be implemented with linked list for an input graph. Note: You are not allowed to use dynamic allocation features of your programming language. For example, in Python you are not allowed to use array, list, or dictionary. This means that you must implement your own linked list. The input is stored in a .csv file like this: You have to read data from file. The intersection names and the maps are for visualization only and you do not need to create or print them. PLEASE USE JAVA!!!
Suppose there are two singly linked lists both of which intersect at some point and become a single linked list. The head or start pointers of both the lists are known, but the intersecting node is unknown. Also, the number of nodes in each of the list before they intersect are unknown and both the list may have it different. List1 may have n nodes before it reaches intersection point and List2 might have m nodes before it reaches intersection point where m and n may be m = n, m > n or m < n. Give an algorithm for finding the merging point. Hints: A brute force approach would be to compare every pointer in one list with every pointer in another list. But in this case the complexity would be O(mn)
Suppose 1,000 Integer elements are generated at random and are inserted into a sorted linked list and a binary search tree (BST) separately. Considering the efficiency of searching for an element in the two structures, which of the following statements is true? The search operation on the list takes longer time because the numbers are not sorted. The search operation will take the same time in both structures. The search operation on the BST takes shorter time because it is relatively balanced. None of these. The search operation on the BST takes longer time because the numbers are not sorted.
Consider a single-linked list of numbers. Write an algorithm to delete a node Before a certain node. The algorithm ask user to input a number and then searches the linked list. If such a node with input value is found algorithm deletes the previous node, otherwise, it reports that such a node is not found.
Given a circular linked list, implement an algorithm that returns the node at the beginning of the loop.DEFINITIONCircular linked list: A (corrupt) linked list in which a node's next pointer points to an earlier node, soas to make a loop in the linked list.EXAMPLEInput:Output:A -> B -> C -> D -> E -> C [the same C as earlier]C
Correct answer will be upvoted else downvoted. Computer science. You are given an exhibit a comprising of n (n≥3) positive integers. It is realized that in this exhibit, every one of the numbers with the exception of one are something very similar (for instance, in the cluster [4,11,4,4] all numbers aside from one are equivalent to 4). Print the list of the component that doesn't rise to other people. The numbers in the cluster are numbered from one. Input The main line contains a solitary integer t (1≤t≤100). Then, at that point, t experiments follow. The main line of each experiment contains a solitary integer n (3≤n≤100) — the length of the exhibit a. The second line of each experiment contains n integers a1,a2,… ,an (1≤ai≤100). It is ensured that every one of the numbers aside from one in the an exhibit are something very similar. Output For each experiment, output a solitary integer — the list of the component that isn't equivalent to other people.

In this lab the task is to write a program that maintains a personal phone book. The program allows to: ▪ Add and Delete entries from the phone book, ▪ Search the phone book for a specific entry by last name or by phone number, and ▪ Print out the entire entries in the phone book. The data in the phone book is maintained by storing in memory with the use of a singly linked list, with one list node per entry. Each node contains members for storing a person’s family name, first name, address, and the phone number. Use strings to store this information. The linked list must be kept in increasing alphabetical order, sorted by family name. There are no duplicate entries with the same family name allowed in the phone book. This program should be menu driven, with the user being offered a choice of the following commands described below: ▪ Insert a new entry into the phone book. The program should prompt the user for a new family name and first name, an address and a phone number. This…
