Note: Consider up(upper bound) as high and lb(lower bound) as low. In this program, the compiler will ask the user to enter the number of elements and then after sorting the compiler will print all the sorted elements on the screen. No additional data structure is required. Data in multi dimensional arrays are stored in tabular form (in row major order). In C/C++, we can define multi dimensional arrays in simple words as array of arrays. A matrix can be represented as a table of rows and columns. However, in all cases, it performs efficiently. The two dimensional (2D) array in C programming is also known as matrix.
This occurs when the array is already sorted or if the elements are in the reverse order.
Therefore, the Worst-case Time complexity=O(n^2). This will happen when the pivot either the smallest or the largest element. All elements are either in the left or the right partition. This occurs when the pivot does not partition the array. This will ensure that the array splits into equal parts each time. The best-case time complexity is achieved if the median is chosen as the pivot. Therefore, the Best case Time complexity= O(n log2n). In each Iteration, the total number of elements to be compared is n. Algorithm for Quick Sort algorithm QuickSort(list) Pre: list 6 fi Post: the list has been sorted in ascending order if list.Count 1 // list already. The total number of iterations taken in log2n (here 2 is the base).
