一、四向链表，输入n生成一个多维4向链表

    @Datastatic class ListNode<T>{private T val;ListNode<T> up,down,left,right;public ListNode(T val){this.val = val;}}public static void main(String[] args){ListNode<Integer> node = getResult(8);ListNode<Integer> row = node;while(row != null){ListNode currNode = row;while(currNode != null){System.out.print(currNode.val + "  ");currNode = currNode.right;}System.out.println("");row = row.down;}}public static ListNode<Integer> getResult(int n){if(n<=0){return null;}ListNode<Integer> head = new ListNode<>(11);head.left = null;head.up = null;ListNode<Integer> current = head;for(int i = 2 ; i <= n ; i++){ListNode<Integer> node = new ListNode<>(10 + i);current.right = node;node.left
