- Merge 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_forwardArray x is [a, b, c, . . . , y] has 25 integers. To find median of medians we form five sub-arrays: [d, c, b, e, a], [i, f, h, j, g], [1, m, k, n, o], [p, s, q, r, t], [w, x, v, u, y]. We find median from these sub-arrays and generate new sorted array [k, h, q, b, v]. Median of new sorted array is q, so median of medians is q. List all elements guaranteed to be greater or equal to q.arrow_forwardQuestion Consider the following definition of a MysteryBox object: public class MysteryBox { private final int x0, x1, x2, x3; private final double y0; private final boolean z0; private final long[] a = new long [248]; } Using the 64-bit memory cost model from lecture, how many bytes does each object of type MysteryBox consume? Include all memory referenced by the object (deep memory). Answer Your answer should be a positive integer that is a multiple of 8.arrow_forward
- I am learning the Algorithm for Order Statistics with the Select Recursive Procedure as shown in the pictures. In the algorithm, we separate out n into separate sequences of 5 elements each or n/5. I was wondering if the same algorithm would work if you did n/6, n/7, or n/10 instead and why. Thank you.arrow_forwardBelow is an array of elements that can be traversed via Linear and Binary search. You will be given five elements for each searching algorithms. You need to list down the elements traversed until it reaches to the element we are looking for: 33 54 74 124 148 248 274 203 443 445 452 457 470 512 520 505 2 10 11 12 13 14 15 570 500 634 730 783 803 810 886 030 10 17 18 19 20 21 22 23 24 25 20 27 28 29 30 31 A.
