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 approach.
-
Iterative Function:
- The time complexity of the iterative approach depends on the algorithm used for distribution.
- If we consider a simple algorithm that iterates through the given set of x and assigns each element to y, the time complexity would be O(n), where n is the size of the input set x.
- In terms of complexity analysis, the iterative approach may have better performance for smaller datasets due to its straightforward implementation.
- The time complexity of the iterative approach depends on the algorithm used for distribution.
-
Recursive Function:
- The time complexity of the recursive approach also depends on the algorithm used and the number of recursive calls.
- If we implement a recursive function that divides the set of x into smaller subsets and assigns them to y, the time complexity would also be O(n), where n is the size of the input set x.
- However, recursive functions may incur additional overhead due to function call overhead and stack usage, which can impact performance for larger datasets.
- In terms of complexity analysis, both approaches have the same time complexity, but the recursive approach may have higher overhead for larger datasets due to recursion.
Pleas explain the Best case, Worst case, and Average case scenario of Iterative Function, Recursive Function, merge sort, and binary search. Also, show their space complexity and T(n) equations and how they are derived by calculations.

- The best case behaviour occurs for quick sort when the partition function splits the sequence of size n into subarrays of size: Select one: a.n/4 : 3n/4 b.n/4 : 3n/2 c.3n/8 : (5n/8) d.n/2 : (n/2)-1 e.n/2 : n/3arrow_forwardUsing Bubble Sort for 1,000,000 numbers is not recommended due to its inefficiency. For sorting large datasets, you should consider faster algorithms like Quick Sort, Merge Sort, or Shell Sort, which have much better time complexity.arrow_forwardPlease justify your answer: Some sorting algorithms require extra space, apart from the space needed for the original array that needs to be sorted.

- The algorithm: –In an array of n elements, go to index [n/2] –If the record there is the one you want, you are done –If the record value there is smaller than your search value, all records less than the current record can be ignored – set your search range of elements to [n/2+1...n] and return to step 1 –Otherwise, set your range of elements to [0...(n/2)-1] and return to step 1 –Repeat this loop until you have 0 elements (record is not found) or record is found Short answer Another approach to the update algorithm is to perform use the delete function for the old value and if it is successful, call the insert function using the new value. Explain in your own words if you think this approach is significantly better, worse, or in the same category as the algorithm discussed in the slides, and why.arrow_forwardWrite the algorithm which finds the second maximum value of the array.

- Select all the statements that are false, bubble sort is defined below:* Quicksort is the fastest sorting algorithm If you are lucky, you can get O(n) time complexity in Mergesort On the worst case, Bubble sort will give you O(n logn) time complexity Average time complexity of insertion sort is much better than bubble sort Selection sort has the worst space complexity among all the sorting algorithmarrow_forwardWith the Binary Search algorithm, the algorithm can be developed by the loop-based form as well as a recursive form. Which of the following is not true? O If the item is not found, the loop version returns when the range bounds reach, but the recursive version finishes when the recursive depth is more than half the initial search range. The search range starts with the whole array, and only the recursive version can work on a subrange passed through arguments. O Both forms of the program divide the search range repeatedly in half. O If the item is found, the loop version returns from the entire method, whereas the recursive version returns from one level of recursion.arrow_forwardCompare the sorting times of the insertion sort with QuickSort using a small array (less than 20).
