Sorted Insert for Circular Linked List
JAVA Program to Sort a Circular Linked List while Inserting Nodes in it
As we’ve learned in the earlier pages that Insertion can be done at various Positions in a Circular Linked List. In this page we’ll learn how we can use those techniques to create program using which we can insert nodes in a Circular Linked List and Sort the list Simultaneously. Below is a Solution in the form of a JAVA Program for Sorted Insert for Circular Linked List along with a detailed analysis of example.
Algorithm that will be used in the Program below
- sortedInsert(Node nextNode)
- Node thisNode = head
- IF thisNode == null
- nextNode->next = nextNode
- head = nextNode
- ELSE IF (thisNode->element >= nextNode->element)
- FOR i=0 until thisNode->next != head
- thisNode = thisNode->next
- thisNode->next = nextNode
- nextNode->next = head
- head = nextNode
- FOR i=0 until thisNode->next != head
- ELSE
- WHILE thisNode->next != head && thisNode->next->element < nextNode-> element
- thisNode = thisNode->next
- nextNode->next = thisNode->next
- thisNode->next = nextNode
- WHILE thisNode->next != head && thisNode->next->element < nextNode-> element
- EXIT
void sortedInsert(int n)
{
Node nextNode=new Node(n);
Node thisNode = head;
if (thisNode == null)
{
nextNode.next = nextNode;
head = nextNode;
}
else if (thisNode.element >= nextNode.element)
{
for (int i=0; thisNode.next != head; i++)
thisNode = thisNode.next;
thisNode.next = nextNode;
nextNode.next = head;
head = nextNode;
}
else
{
while (thisNode.next != head && thisNode.next.element < nextNode.element)
thisNode = thisNode.next;
nextNode.next = thisNode.next;
thisNode.next = nextNode;
}
}

}
}
int cnt;
static Node list1, list2;
public Node head = null;
public Node tail = null;
public void print() {
Node current = head;
if(head == null) {
System.out.println("Empty List");
}
else {
System.out.println("Circular Linked List is");
do{
//Prints each node by incrementing pointer.
System.out.print(" "+ current.element);

}while(current != head);
System.out.println("\n");
}
}
void sortedInsert(int n)
{
Node nextNode=new Node(n);
Node thisNode = head;
if (thisNode == null)
{

head = nextNode;
}
else if (thisNode.element >= nextNode.element)
{
for (int i=0; thisNode.next != head; i++)
thisNode = thisNode.next;
thisNode.next = nextNode;
nextNode.next = head;
head = nextNode;
}
else
{
while (thisNode.next != head && thisNode.next.element < nextNode.element)
thisNode = thisNode.next;
nextNode.next = thisNode.next;
thisNode.next = nextNode;
}
}
}
Output
Circular Linked List is 10 20 30 40 50 60 Linked List after insertion : Circular Linked List is 10 20 30 33 40 50 60

}
else if (thisNode.element >= nextNode.element)
{
for (int i=0; thisNode.next != head; i++)

thisNode = thisNode.next;
nextNode.next = thisNode.next;
thisNode.next = nextNode;
}
}
}
Output
Original List Circular Linked List is 10 20 30 40 50 60 List after insertion Circular Linked List is 10 20 30 33 40 50 60
