Homework Answers
Travelling sales man problem is a problem in which a sales person has list of cities with distances between two cities, we have to find the shortest possible route that we can visit all cities and return to the original city.
So many great computer scientists worked on this problem but they failed miserably to prove worst-case time complexity is better than exponential. Yet, no one has ever proven that such an algorithm is impossible.

Worst-case complexity of quicksort is similar to the every-case complexity of exchange sort. Average-case time complexity of quicksort is as good as worst-case time complexity of mergesort. Similar to quicksort, mergesort uses a pivot to partition the input array. Select one: True False

What is the worst-case asymptotic time complexity of the following divide-andconquer algorithm (give a Θ-bound). The input is an array A of size n. You may assume that n is a power of 2. (NOTE: It doesn’t matter what the algorithm does, just analyze its complexity). Assume that the non-recursive function call, bar(A1,A2,A3,n) has cost 3n. Show your work! Next to each statement show its cost when the algorithm is executed on an imput of size n abd give the...

THESE ARE TRUE/FALSE The best-time complexity for insertion sort is O(nlogn). The worst-time complexity for bubble sort is O(nlogn). A linked structure consists of nodes. Each node is dynamically created to hold an element. All the nodes are linked together to form a list. The time complexity for searching an element in a binary search tree is O(logn) The time complexity for inserting an element into a binary search tree is O(logn). In an AVL tree, the element just inserted...
