Easiest Solution

public static SinglyLinkedListNode deleteNode(SinglyLinkedListNode head, int index) { SinglyLinkedListNode temp = head;

    if(index == 0){
        head = head.next;
    }else {
       for(int i = 0; i < index - 1; i++){
           temp = temp.next;
        }
        temp.next = temp.next.next;
    }
    return head;

}
