Question
Java -
- Two of your co-workers (Sam and Kris) both wrote a different unique sorting
algorithm . Initial tests (with 50 data elements) show that Kris’ program ran approximately 5x faster (Sam’s took 5x as long to complete). As the chief engineer, you need to figure out which one to use – Should Sam’s program be dropped in favor of Kris’? Is Kris’ better? Why or why not? What other tests would you run (what other criteria would you be looking for)? Make sure you explain your answer.

- A given implementation of bubble-sort takes on average 1 second to sort an array of 1000 elements. How many seconds do you expect sorting an array of 8000 elements will take? A given implementation of quicksort takes on average 0.1 seconds to sort an array of 1000 elements. How many seconds do you expect sorting an array of 8000 elements will take?arrow_forwardThe time complexity of this program is not O (log n). This actually looks like it was pulled from another website.. In other programming languages, we use a matrix (shown below) as a means of getting the Fibonacci nth number. We raise it to (n-1), though I don't know how to create this in Oz since I don't think it uses matrices. Can this be re-analyzed please? Thanks! 1 1 1 0arrow_forwardYou want to design an algorithm, called minMax(A,p,r), that takes an array of integers and indexes of the first and last elements, and returns the minimum and maximum values in that range. Now write the pseudo code of a divide and conquer (and therefore, recursive) algorithm with the same time complexity (Θ(n)). You can assume that p ≤ r. Also, in your code, you can return two numbers by returning a pair, e.g. “return (a, b)”, and can save the output in a similar way, e.g. “(a, b) = minMax(parameters)”. (Short answer please)arrow_forward
- Using Oz Programming, how would one create a program for finding the nth Fibonacci number in the sequence? I know it has matrix, though I can't seem to get that working in Oz. The main goal was finding an implementation with an O (log n) time complexity. Thanks!arrow_forwardMerge sort is an efficient sorting algorithm with a time complexity of O(n log n). This means that as the number of elements (chocolates or students) increases significantly, the efficiency of merge sort remains relatively stable compared to other sorting algorithms. Merge sort achieves this efficiency by recursively dividing the input array into smaller sub-arrays, sorting them individually, and then merging them back together. The efficiency of merge sort is primarily determined by its time complexity, which is , where n is the number of elements in the array. This time complexity indicates that the time taken by merge sort grows logarithmically with the size of the input array. Therefore, even as the number of chocolates or students increases significantly, merge sort maintains its relatively efficient performance. Regarding the distribution of a given set of x to y using iterative and recursive functions, the complexity analysis depends on the specific implementation of each…arrow_forwardThe interchange implementation was supposed to be better than the transpose implementation as it implements the same algorithm without the need of copying the 640,000 elements. However, it is not. How do you explain this inconsistency?arrow_forward
- You are building a simulation and need to generate X ~ norm(506.5, 83.5725). Given the following U ~ unif[0,1], calculate the corresponding values of X: U = {0.8864,0.6067,0.366} Note: the following should help if you are using R. U: 0.8864, 0.6067, 0.366 Please enter your answers to four decimal places: U1= 0.8864 => X1 = U2=0.6067 => X2 = U3=0.366 => X3=arrow_forwardAnswer the given question with a proper explanation and step-by-step solution. javaarrow_forwardConsider sorting a list of items that are in reverse sorted order. If you were forced to pick between the three iterative sorting algorithms (bubble sort, selection sort, or insertion sort) to work through this set and place it into normal (ascending) sorted order, which would you pick and why?arrow_forward
