quick sort is a divide and conquer method , it is not dynamic programming
Yes, Quick Sort is an in-place sorting algorithm.
The memory complexity of the quick sort algorithm is O(log n) in the best case and O(n) in the worst case.
The space complexity of the quick sort algorithm is O(log n) in the best and average cases, and O(n) in the worst case.
The space complexity of the Quick Sort algorithm is O(log n) in the best and average cases, and O(n) in the worst case.
The time complexity of the quick sort algorithm is O(n log n) in the average case and O(n2) in the worst case.
The worst case time complexity of the quick sort algorithm is O(n2), where n is the number of elements in the input array.
Dynamic programming and memoization are both techniques used to optimize the efficiency of solving complex problems by storing and reusing intermediate results. The key difference lies in their approach: dynamic programming solves problems by breaking them down into smaller subproblems and solving them iteratively, while memoization stores the results of subproblems to avoid redundant calculations. Dynamic programming can be more efficient for problems with overlapping subproblems, as it avoids recalculating the same subproblems multiple times. However, it may require more space and time complexity due to the iterative nature of solving subproblems. On the other hand, memoization can be more effective for problems with a recursive structure, as it stores the results of subproblems in a table for quick access. This can reduce the time complexity of the algorithm, but may require more space to store the results. In summary, dynamic programming is more suitable for problems that can be solved iteratively, while memoization is better for recursive problems. The choice between the two techniques depends on the specific problem and the trade-off between time and space complexity.
* In a typeless language, a variable can contain any kind of value (numeric, string, boolean). * Typeless languages are very flexible and dynamic, resulting in quick turn around of code.
You don't waste time computing a pivot.
The most efficient sorting algorithm available is the Quick Sort algorithm. It has an average time complexity of O(n log n) and is widely used for its speed and efficiency in sorting large datasets.

Use a sorting algorithm. There are a bewildering number of sorting algorithms, both stable and unstable. To sort numbers, an unstable sort suffices. The algorithm you use will depend on how many numbers need to be sorted (a small or a large set), however a hybrid algorithm (a combination of two or more algorithms) can cater for both. Introsort (unstable) and timsort (stable) are the two most common hybrid sorting algorithms.
