Show detailed workout. Give your logical reasoning, where required, in simple and comprehensivesentences.
1. Stable sorting algorithms maintain the relative order of records with equal keys (i.e. values). That is, a sorting algorithm is stable if whenever there are two records R and S with the same key (i.e. value) and with R appearing before S in the original list, R will appear before S in the sorted list. Consider Insertion Sort, Merge Sort, Quick Sort. Which of these is not a stable sorting algorithm? Justify your answer.
Please Help ASAP!!!!
Please solve using C++
This question concerns the following sorting algorithm (attachment). (b) Consider the operation of SORT on a list of length N. How many comparisons in line 4 take place when i = 1 and when i = N-1? (c) How many comparisons take place in total? Show your working. You may use the result 1+2+...+n=n[(n+1)/2] (d) Based on the analysis above, or otherwise, what is the worst, best and average- case time complexity of SORT? Explain your answer.
You have the list [9, 73, 89, 20, 94, 83, 57] and it needs to be sorted in place. Based on the pass status of the list during the sorting process (where all swap operations happen in place), which of sorting algorithms is being used based on the sort process below? Please explain the reason for the choice too...
Please only answer part 2 (ii) java
Below is the exercise for unsorted arrays. True or False: For each statement below, indicate whether you think it is True or False 3) For the insert function, if the array is empty, there are no comparison operations that need to be performed and you can immediately add the new element 5) Because the update algorithm depends on using linear search, its performance is O(1) in the worst case scenario 6) If you search for and delete an element in an unsorted array and then shift the rest of the elements to fill the hole, the worst case performance is O(n) 7) If you search for and delete an element in an unsorted array and then move the last element to fill the hole, the worst case performance is O(n)
(b) Explain in your own words why even the more efficient versions of bubble sort are considered to be slow algorithms. Illustrate your answer using the example data: {17, 15, 11, 13}
Please justify your answer: Some sorting algorithms require extra space, apart from the space needed for the original array that needs to be sorted. Which one of the following statements on the space usage of sorting algorithms is correct? a.) A Heapsort for sorting an array of size N requires an amount of extra space proportional to N. b.) Insertion Sort for sorting an array of size N requires an amount of extra space proportional to N. c.) Merge sort for sorting an array of size N requires an amount of extra space proportional to N. d.) Quicksort for sorting an array of size N requires an amount of extra space proportional to N. e.) None of the above
Please help with question: Determine the running time of the following algorithms. Write summations to represent loops and simplify. Show all work. If bounding is used, the upper and lower bounds must only differ by a constant. Note: This is not the line-by-line analysis method. Loops are inclusive.
