What is the space complexity of shell sort?
average case worst case LSD Radix sort O(n.k/s) O(n.k/s) MSD Radix sort O(n.k/s) O(n.k/s.2^s) n=no of items to be sorted k=size of each key s=chunk size used by implementation LSD=Least Significant Digit MSD=Most Significant Digit
How do you write a c plus plus program to sort a vector of strings using MSD radix sort?
The standard library sort algorithm automatically uses MSD radix to sort strings: std::vector<std::string> vs = {"a", "b", "c" "d", "ab"}; std::sort(vs.begin(), vs.end()); After sorting, the order will be: {"a", "ab", "b", "c", "d"}
How do you select pivot in quick sort?
quick sort has a best case time complexity of O(nlogn) and worst case time complexity of 0(n^2). the best case occurs when the pivot element choosen as the center or close to the center element of the list.the time complexity can be derived for this case as: t(n)=2*t(n/2)+n. whereas the worst case time complexity for quick sort happens when the pivot element is towards the end of the list.the time complexity for this can be derived using the recurrence eqn: t(n)=t(n-1)+n
What is the complexity of bucket sort?
o(n)
Is selection sort and tournament sort are same?
No. Tournament sort is a variation of heapsort but is based upon a naive selection sort. Selection sort takes O(n) time to find the largest element and requires n passes, and thus has an average complexity of O(n*n). Tournament sort takes O(n) time to build a priority queue and thus reduces the search time to O(log n) for each selection, and therefore has an average complexity of O(n log n), the same as heapsort.
What is the time complexity of Radix Sort in terms of Big O notation?
The time complexity of Radix Sort is O(nk), where n is the number of elements in the input array and k is the number of digits in the largest element.
What are the key differences between radix sort and quicksort in terms of efficiency and performance?
Radix sort and quicksort are both sorting algorithms, but they differ in their approach and efficiency. Radix sort is a non-comparative sorting algorithm that sorts numbers by their individual digits, making it efficient for sorting large numbers. Quicksort, on the other hand, is a comparative sorting algorithm that divides the list into smaller sublists based on a pivot element, making it efficient for sorting smaller lists. In terms of performance, radix sort has a time complexity of O(nk), where n is the number of elements and k is the number of digits, while quicksort has an average time complexity of O(n log n). Overall, radix sort is more efficient for sorting large numbers with a fixed number of digits, while quicksort is more efficient for general-purpose sorting.
What is the running time of radix sort algorithm?
The running time of the radix sort algorithm is O(nk), where n is the number of elements to be sorted and k is the number of digits in the largest element.
Is radix sort an in-place sorting algorithm?
Yes, radix sort is an in-place sorting algorithm.
What is the space complexity of shell sort?

What is the running time of heap sort algorithm in terms of time complexity?
The running time of the heap sort algorithm is O(n log n) in terms of time complexity.
What is the time complexity of heap sort algorithm?
The time complexity of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
What are some examples of algorithms that exhibit quadratic time complexity?
Some examples of algorithms that exhibit quadratic time complexity include bubble sort, selection sort, and insertion sort. These algorithms have a time complexity of O(n2), meaning that the time it takes to execute them increases quadratically as the input size grows.
What is the time complexity of quick sort algorithm?
The time complexity of the quick sort algorithm is O(n log n) in the average case and O(n2) in the worst case.
What is the time complexity of the best case scenario for Bubble Sort?
The time complexity of the best case scenario for Bubble Sort is O(n), where n is the number of elements in the array.
