# 1. Introduction

Sorting is a process that arranges elements in a particular order. Sorting arrays, specifically in ascending order, is fundamental in a myriad of applications, be it in data analytics, database systems, or even in our day-to-day tasks like organizing contacts. While Go offers built-in slice sorting, there's merit in understanding the basics. This blog post will take you on a journey through a Go program that sorts an array in ascending order from the ground up.

# 2. Program Overview

Our bespoke Go program will:

1. Create an array with numbers.

2. Implement a sorting algorithm to align these numbers in ascending order.

3. Showcase the freshly sorted array to the user.

# 3. Code Program

``````// The main package declaration.
package main

// The trusty fmt package is marshaled for our I/O maneuvers.
import "fmt"

// Our sorting function, using the timeless Bubble Sort algorithm.
func bubbleSort(arr []int) []int {
n := len(arr)
for i := 0; i < n-1; i++ {
for j := 0; j < n-i-1; j++ {
if arr[j] > arr[j+1] {
// A classic swap maneuver.
arr[j], arr[j+1] = arr[j+1], arr[j]
}
}
}
return arr
}

// The epicenter of our program, the main function.
func main() {
array := []int{64, 34, 25, 12, 22, 11, 90}
fmt.Println("Original Array:", array)

// The array undergoes the sorting process.
sortedArray := bubbleSort(array)
fmt.Println("Sorted Array:", sortedArray)
}
``````

### Output:

```The program, upon its noble execution, will exclaim:
Original Array: [64 34 25 12 22 11 90]
Sorted Array: [11 12 22 25 34 64 90]
```

# 4. Step By Step Explanation

1. The program starts with the main package declaration.

2. It imports the "fmt" package for input-output operations.

3. A bubbleSort function is defined to sort an array of integers.

4. Inside the function, the array's length is determined. Two nested loops are used to repeatedly traverse the array and compare adjacent elements.

5. If an element is larger than its adjacent element, they are swapped.

6. This process continues until the entire array is sorted.

7. The main function is then defined. Within the main function, an integer array is declared with some initial values.

8. The original array is displayed on the screen.

9. The bubbleSort function is called to sort the array.

10. The sorted array is then displayed on the screen.
