What is ASC sorting?
ASC (Ascending) sorting is a method of arranging elements in a sequence (for example, in an array or list) in increasing order. It is based on comparing elements and rearranging them to achieve the appropriate order.
The ASC sorting process involves sequentially comparing two adjacent elements and swapping them if they do not match the appropriate order. In each pass, the largest (or smallest) element is placed in its correct position. This process is repeated for all elements until complete ordering is achieved.
ASC sorting is one of the simplest sorting algorithms, but its efficiency depends on the size of the input data. In the case of a large number of elements, it may be inefficient compared to other algorithms, such as quicksort (QuickSort) or merge sort (MergeSort), which have better complexity.
How to perform ASC sorting in SQL?
SELECT column_name FROM table_name ORDER BY column_name ASC;
How to perform ASC sorting in JS (JavaScript)?
const arr = [5, 2, 8, 1, 6]; arr.sort((a, b) => a - b); console.log(arr);
How to perform ASC sorting in Ruby?
arr = [5, 2, 8, 1, 6] arr.sort! puts arr
What is DESC sorting?
DESC (Descending) sorting is a method of arranging elements in a sequence (for example, in an array or list) in decreasing order. It is the opposite of ASC sorting, as the elements are arranged in reverse order.
The DESC sorting process involves comparing two adjacent elements and rearranging them if they do not match the appropriate order. In each pass, the smallest (or largest) element is placed in its correct position. This process is repeated for all elements until complete ordering is achieved.
DESC sorting is also one of the simplest sorting algorithms. In many programming languages and database management systems (for example, SQL), DESC is the default sorting order unless other settings are specified.
How to perform DESC sorting in SQL?
SELECT column_name FROM table_name ORDER BY column_name DESC;
How to perform DESC sorting in JS (JavaScript)?
const arr = [5, 2, 8, 1, 6]; arr.sort((a, b) => b - a); console.log(arr);
How to perform DESC sorting in Ruby?
arr = [5, 2, 8, 1, 6]
arr.sort! { |a, b| b <=> a }
puts arr
ASC and DESC are the simplest sorting methods. To remember the direction of sorting - just refer to the corresponding English words. ASC (Ascending) and DESC (Descending).
