Sorting is the process of arranging data in ascending or descending order based on a linear relationship between the data items.

Names, numbers, and records can all be sorted. For example, because the names in the phone book have been arranged into alphabetical order, it is quite easy to seek up a friend's phone number from a telephone dictionary.

Sorting is the process of arranging data in a preferred order in a data structure. Sorting data makes it easier to swiftly and simply search through it. A dictionary is the most basic example of sorting. When you wanted to look up a term in a dictionary before the Internet, you had to do it in alphabetical order. This made things a lot easier.

In this article, we will learn about sorting algorithms, types of sorting. So let’s get started.

What Is a Sorting Algorithm?

A sorting algorithm is nothing more than a set of instructions or orders. An array is used as an input, and the sorting algorithm executes operations on it to produce a sorted array.

In their computer science lessons, many pupils would have learned to sort data structures. It is introduced at a young age to help curious children get an understanding of more advanced computer science concepts such as divide-and-conquer algorithms, binary trees, heaps, and so on.

Types Of Common Sorting Algorithm:

Insertion:

Sorting is accomplished using this method by putting elements into an already sorted list. There is only one element in the sorted list at first. Other items are gradually added to the list in the correct order.

Merge Sort:

The elements are separated into partitions in this manner until each partition has sorted elements. The components are then properly positioned and the partitions are merged to produce a fully sorted list.

Quick Sort.

This method identifies a pivot element, which is then fixed in its position by moving all elements less than it to the left and all elements greater than it to the right.

Radix Sort:

Sorting is done using this method depending on the number's place values. The less significant digits are sorted first in this approach. When all the numbers are sorted on a more significant digit, those with the same digit in that place but different digits in the less-important position are already sorted on the less-significant position.

Heap Sort:

The file to be sorted is regarded as a binary tree in this approach. The heap sort is implemented using an array, which is a sequential representation of a binary tree.

The essential idea behind sorting an array is that its members are initially in random order and must be ordered from lowest to highest.

Selection sort:

The first element is chosen and compared to all other items in this procedure. If any other element is less than the first, it should be swapped out. By the end of this comparison, the least element in the array will be at the very top. This is referred to as pass1. The second element is chosen in pass II and compared against all other items. If any other element is less than the selected element, it will be swapped. This operation will continue until the array has been sorted.

When the number of passes in an array is compared to the array's size, the result is –1.

Bubble sort:

This method compares the last element to the one before it. If the last element is less than the preceding element, the elements are swapped. The preceding element is then compared to the preceding element. This procedure repeats itself until the II and I elements are compared. The first pass is referred to as pass 1.

The number of passes would be equal to the array size –1.
