Which code block uses bubble sort?

[pixielott]

Hey,
May I know which one is bubble sort from here:

1)

Código [Seleccionar] Expandir

for(int i=0;i<n-1;i++)
  for(int j=n-1; j>i;j--)
    if(a[j] < a[j-1])
        swap(a[j], a[j-1]);

2)

Código [Seleccionar] Expandir

for(int i=0; i<n-1; i++)
  for(int j=i+1; j<n; j++)
    if(a[j] < a[i])
        swap(a[j],a[i]);

3)

Código [Seleccionar] Expandir

int temp, i, j = 0;
    boolean swaped = true;

    while (swaped) {
        swaped = false;
        j++;
        for(i = 0; i < arr.length - j; i++){
            if(arr[i] > arr[i+1]){
                temp = arr[i];
                arr[i] = arr[i+1];
                arr[i+1] = temp;
                swaped = true;
            }
        }
    }

IMO, the first is bubble sort, not sure of the second and third.

Hi!

The 2nd one is bubble sort.

Cheers!

PS: In case you didn't notice, this is a spanish talking forum. I'm sure you could find any in hindi language.
