Write an array that when sorting using Selection Sort, requires O(n^2) time complexity and only O(n) using Insertion Sort. Provide explanations for how you got your answer.
After one pass of the Quick Sort we know that: O the largest value is in its correct location. O the smallest value is in its correct location. O the values in the array are pairwise sorted. O the splitVal is in its correct location. O None of these is correct.
Quicksort is a powerful divide-and-conquer sorting algorithm that can be described in just four lines ofpseudocode. The key to Quicksort is the PARTITION(A, p, r) procedure, which inputs elementsptorof array A,and chooses the final element x = A[r] as the pivot element. The output is an array where all elementsto the left ofxare less thanx, and all elements to the right of x are greater than x. In this question, we will use the Lomuto Partition Method from class and assume that the pivot isalwaysthe last (right-most) element of the input array. Question: Let A be an array withn= 2k−1 elements, where k is some positive integer. Determine a formula (in terms of n) for the minimum possible number of total comparisons required by Quicksort, as well as a formula for the maximum possible number of total comparisons required by Quicksort. Use your formulas to show that the running time of Quicksort is O(nlogn) in the best case and O(n2) in the worst case.
Assume that we have a sorted list in an array: Index: 0 1 2 3 4 5 6 7 8 9 10 11 numbers: 12 15 17 19 22 26 28 30 32 34 36 38 we want to use the binary search algorithm to find the value 19 in the list. What would be the indexes of the array that the binary search would check to find the value 19 the indexes and not the actual numbers in the list otherwise
Write the algorithm which sorts the array by using the merge sort algorithm. Then find the complexity of the algorithm as Big 0 notation

Assume nums is an array of integers that looks like this: -3 12 9 0 2 -1 If we are sorting from smallest to largest, what will nums look like after 2 times through the outside loop if we are using bubble sort? Note: When you're entering the values, make sure you leave at least one space between them. Would it be possible to perform a linear search on a 2-D array? Answers: Yes, but you would be limited to using only one loop No, because a 2-D array is not stored in linear fashion in RAM Yes, as long as you used the proper nested loops No, you would have to use a binary search Yes, but only if the array's elements were sorted
Write the algorithm which finds the second maximum value of the array. Then find the complexity of the algorithm as Big O notation
