What is the running time of Binary Search if we use it to search for a number in a sorted linked list? Explain your answer
Homework Answers
Binary search works effectively for arrays, because in its each
iteration it accesses the mid value(middle index of current
array),
so, accessing mid value is performed in O(1) time in arrays, but in
sorted linked list it will take O(n) to access it
hence complexity of binary search will become O(nlogn) in case of
sorted linked list, //n for locating mid index, and logn for
searching key

We know that binary search on a sorted array of size n takes O(log n) time. Design a similar divide-and-conquer algorithm for searching in a sorted singly linked list of size n. Describe the steps of your algorithm in plain English. Write a recurrence equation for the runtime complexity. Solve the equation by the master theorem.

Binary Search
Suppose we want to check if a sorted sequence A contains an element v. For this, we can use Binary Search. Binary Search compares the value at the midpoint of the sequence A with v and eliminates half of the sequence from further consideration. The Binary Search algorithm repeats this procedure, halving the size of the remaining portion of the sequence each time. Write a recurrence for the runningtime of Binary search and solve this recurrence.

In C++ Given a pointer to the root of a binary search tree (has left, right, and parent pointers as well as a data section ) write a function (or functions) which will return an STL list (you should not define this class, it’s already included) with all of the values from the tree in sorted order. Your code should run in theta(N) time. for the second part,.given a pointer to the first node of a linked list, you are...

C++ Time the sequential search and the binary search methods several times each for randomly generated values, then record the results in a table. Do not time individual searches, but groups of them. For example, time 100 searches together or 1,000 searches together. Compare the running times of these two search methods that are obtained during the experiment. Regarding the efficiency of both search methods, what conclusion can be reached from this experiment? Both the table and your conclusions should...

What are the main characteristics of a binary search tree? In your opinion, what advantages does a binary search tree have over a linked list or an array? Assuming you want to create a binary search tree of integers, draw the resulting tree if the integers input were as follows : 25 43 12 20 5 50 30
