Here is the solution of Compare two linked lists Click Here

   if(head1==NULL && head2!=NULL){
        return false;
    }
    else if(head1!=NULL && head2==NULL){
        return false;
    }
    else if(head1== NULL && head2== NULL){
        return true;
    }

    while(head1!=NULL && head2!=NULL){
        if(head1->data!=head2->data){
            return false;
        }
        head1=head1->next;
        head2=head2->next;
    }

    if(head1==NULL && head2!=NULL){
        return false;
    }
    else if(head1!=NULL && head2==NULL){
        return false;
    }
    else{
        return true;
    }

All test case passed

static boolean compareLists(SinglyLinkedListNode head1, SinglyLinkedListNode head2) {

    boolean flag = true;

    while (head1 != null && head2 != null){
         if(head1.data != head2.data){
             flag = false;
             break;
         }
         head1 = head1.next;
         head2 = head2.next;
    }

    if(flag == false || head1 != null || head2 != null){
        return false;
    }

    return true;


}

The TypeScript language option seems to be missing the compare_lists function described in the problem statement; the same is true for some of the subsequent challenges.
