To sort in descending order, we can modify the counting sort algorithm. counting_sort_desc.py def counting_sort_desc(arr): max_val = max(arr) count = [0] * (max_val + 1) for num in arr: count[num] += 1 sorted_arr = [] for i in range(len(count) - 1, -1, -1): ...
This modified implementation adds a couple of parameters, left and right, that indicate which portion of the array should be sorted. This allows the Timsort algorithm to sort a portion of the array in place. Modifying the function instead of creating a new one means that it can be reused fo...
the sorted function will return new sorted list from an iterable. The list.sort() function can be used to sort the list in ascending and descending order and takes the argument reverse, which is by default false and, if passed true, then sorts the ...

1function [total] = addition(num_1,num_2) 2total = num_1 + num_2; 3end In this code, you see the function definition on line 1. There is only one output variable, called total, for this function. The name of the function is addition and it takes two arguments, which will be ...
Python uses a system of memory pools to optimize the allocation and deallocation of smaller objects. It improves performance. 17. Differentiate between Sorted vs sort sort() and sorted() are the two built-in methods used to sort objects in Python. However, their features differ in some aspects...
Let's see how to sort a list alphabetically in Python without the sort function. We can use any popular sorting techniques like quick sort, bubble sort, or insertion sort to do it. Let's learn how to do it with Quick sort, which can be two to three times faster. The algorithm's ...
