How to Sort a Array Using Selection Sort
What is Selection Sort?
Selection sort is a sorting algorithm that is used to sort an array of data. It works by first dividing the array into two equal parts, and then sorting the data in the first part using a comparison function. Once the data has been sorted, the algorithm repeats the process with the second part of the array.
Implementing Selection Sort
This blog post will walk you through the steps of sorting an array using Selection Sort. The code for this blog post can be found on GitHub.
In order to implement Selection Sort, we first need to create an array of items. We can do this by creating a new Array object and initializing it with some random data.
var items = new Array(); // create an array with some random data items.push(Math.random());
Next, we need to create a function that will perform the sorting process. This function will take as input an array of items and will return a sorted copy of that array.
When to use Selection Sort
When sorting an array, you may encounter cases where the elements of the array are not in order. In these cases, you can use selection sort to sort the elements. Selection sort is a more efficient way to compare two arrays than using a comparison function, and it is faster than an insertion sort.
The following example shows how to use selection sort tosort an array of integers. The first step is to create an empty sorted list and store it in a variable named ” sorted”. Next, we need to create an array of integers and store it in a variable named ” arr”. We then use the selection Sort() method to sort the integers in arr according to their value. The code for this example is shown below:
sorted = [] arr = [1, 2, 3, 4, 5] # Create an empty sorted list. sorted = SelectionSort(arr) # Store the sorted list in a variable called “sorted”.
When you run this code, you will see that the integers are sorted according to their value. The code for this example is shown below:
# Run the code. print(sorted) 1 2 3 4 5
The Greatest Common Factor
There are a few ways to sort an array using selection sort. The simplest way is to use a for loop and assign the array elements to temporary variables, then use selection sort on each of these variables.
The following code uses a for loop to create three temporary arrays, A, B, and C. It then uses selection sort on each of these arrays.
Dim A(5),B(5),C(5)
For I = 1 To 5
A(I) = Integer(Rnd() * 6)+1
Next I
Select Case A
Case 1
B(I) = C(I)+A(I)*Integer(Rnd()*6)+1
Case 2
B(I) = C(I)+A(I)*Integer(Rnd()*6)+2
Case 3
B(I) = C(I)+A(I)*Integer(Rnd()*6)+3
End Select
The code in this example sorts the original array in reverse order. If you want to sort the array in forward order, you would need to change the code so that it uses Selection
Conclusion
In this article, we are going to learn how to sort a array using the Selection Sort algorithm. This algorithm is very efficient when it comes to sorting large arrays of data, and it is one of the most commonly used algorithms in computer programming. We will also discuss some common issues that can occur while implementing this algorithm, and provide some tips on how to overcome them. By the end of this article, you should be able to implement Selection Sort successfully in your own programs.
