the average time-complexity of the quicksort (the average number of comparisons) is O(n log n). Depending on the data to be sorted, however, the performance may be deteriorated drastically. In the worst case, the time complexity is O(n2).Tadashi Mizoi...
In such a scenario, the pivot element can’t divide the input array into two and the time complexity of Quicksort increases significantly. 3. Worst Case Time Complexity Analysis Let’s assume that we choose a pivot element in such a way that it gives the most unbalanced partitions possible:...
Time Complexity of Randomized Quick Sort Consider the randomized quick sort (i.e. the pivot is randomly chosen). Let the sorted arrayA=[b1,…,bn]A=[b1,…,bn]. PutAij={biis compared tobj}Aij={biis compared tobj}. Sincebibiis compared tobjbjiffbibiorbjbjis first pivot chosen from[bi...
Time complexity, a description of how much computer time is required to run an algorithm. In computer science, time complexity is one of two commonly discussed kinds of computational complexity, the other being space complexity (the amount of memory used

Optimization:Time complexity analysis allows us to make code more efficient, which is crucial in today’s digital world where speed matters. Scalability:It ensures that our software can handle big datasets, making it versatile and capable of growing with our needs. ...
Time & Space Complexity Quick Sort: Time complexity: best case O(n*lgn), worst case O(n^2) Space complexity: Best case O(lgn) -> call stack height Worse case O(n^2) -> call stack height Merge Sort Time complexity: always O(n*lgn) because we always divide the array in halves....

After all, they do roughly the same amount of work so why shouldn't they be treated the same? In practice they might not perform the same but from the Big O time complexity we cannot tell so it's just misleading to treat them differently. zapshe wrote: You are NOT saying you're doi...
