In other words, the algorithm has a recursive structure. 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...

is applied to sort the sequence (2, 12, 16, 88, 1, 5, 10)in ascending order. If the resulting sequences of the first two runs are (2, 12 , 16, 10, 1, 5, 88) and (2, 12, 5, 10, 1, 16, 88), then the algorithm must be ___. A...
In worst-case analysis, we look at the scenario where the algorithm performs the most poorly, taking the maximum amount of time or resources. It helps us understand the upper bound on an algorithm’s performance. We want to know how long the algorithm can possibly take, regardless of the i...
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....
Algorithms may have different time and space complexities for best-case, worst-case, and average-case scenarios. Example: Quicksort has an average-case time complexity of O(n log n) but a worst-case time complexity of O(n2). Understanding Time Complexity: ...

This means the worst-case scenario for how the algorithm will perform. Omega Notation - represents the lower bound of an algorithm. This is the best-case scenario. Theta Notation - represents both the upper bound and lower bound and therefore analyses the average case complexity of an algorithm...

Bubble Sort Time ComplexityThe Bubble Sort algorithm goes through an array of nn values n−1n−1 times in a worst case scenario.The first time the algorithm runs through the array, every value is compared to the next, and swaps the values if the left value is larger than the right. ...
