Example 1: bubble sort in java
public static void bubbleSort(int arr[])
{
for (int i = 0; i < arr.length; i++) //number of passes
{
//keeps track of positions per pass
for (int j = 0; j < (arr.length - 1 - i); j++) //Think you can add a -i to remove uneeded comparisons
{
//if left value is great than right value
if (arr[j] > arr[j + 1])
{
//swap values
int temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
}
Example 2: bubble sort code
func Sort(arr []int) []int {
for i := 0; i < len(arr)-1; i++ {
for j := 0; j < len(arr)-i-1; j++ {
if arr[j] > arr[j+1] {
temp := arr[j]
arr[j] = arr[j+1]
arr[j+1] = temp
}
}
}
return arr
}
Example 3: Algorithm of bubble sort
begin BubbleSort(list)
for all elements of list
if list[i] > list[i+1]
swap(list[i], list[i+1])
end if
end for
return list
end BubbleSort
Example 4: bubble sort algorithm
#include
using namespace std;
void bubbleSort(int arr[], int n){
int temp,i,j;
for(i=0;i arr[j]){
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}
}
int main(){
int arr[] = {1,7,33,9,444,2,6,33,69,77,22,9,3,11,5,2,77,3};
int n = sizeof(arr) / sizeof(arr[0]);
bubbleSort(arr, n);
for(int i=0;i
