Bubble Sort in Go Lang

Go ProgrammingServer Side ProgrammingProgramming

Bubble Sort is a sorting algorithm that works by swapping the elements that are in the wrong order. In multiple passes, it checks if the adjacent elements are in the right order (increasing) or not.

The Time Complexity of the Bubble Sort is O(n^2) since it takes two nested loops to check the adjacent element.

For example, let’s take the following unsorted array −

22 15 11 45 13

Bubble Sort Algorithm first traverses the whole array and then in another loop checks if the adjacent elements are in order or not.

Thus, after sorting the elements will be,

11 13 15 22 45

Algorithm

  • In two nested loops, compare each element with its adjacent element.

  • Swap the element if it is less than the previous element.

  • Print the array.

Example

Implementation of Bubble Sort Algorithm

 Live Demo

package main
import "fmt"
func BubbleSort(array[] int)[]int {
   for i:=0; i< len(array)-1; i++ {
      for j:=0; j < len(array)-i-1; j++ {
         if (array[j] > array[j+1]) {
            array[j], array[j+1] = array[j+1], array[j]
         }
      }
   }
   return array
}
func main() {
   array:= []int{11, 14, 3, 8, 18, 17, 43};
   fmt.Println(BubbleSort(array))
}

Output

Running the above code will sort the given unsorted array and print the output as follows &miuns;

3 8 11 14 18 17 43
