bubble sort for linkedlist code example
Example: bubble sort on a doubly linked list
public void sortList() {
Node current = null, index = null;
int temp;
//Check whether list is empty
if(head == null) {
return;
}
else {
//Current will point to head
for(current = head; current.next != null; current = current.next) {
//Index will point to node next to current
for(index = current.next; index != null; index = index.next) {
//If current's data is greater than index's data, swap the data of current and index
if(current.data > index.data) {
temp = current.data;
current.data = index.data;
index.data = temp;
}
}
}
}
}
