输入一个循环链表,每个结点存一些东西,比如存int 数字,

即构造链表, Node1(存数字3)->Node2(6)-> Node3->Node4->Node1, 然后输入一个位置,比如1, 定位到Node2,从Node2开始每隔三个Node删除一个Node,直到该链表删除完-Enter a circular linked list, each node keep some things, such as deposit int number, that is constructed list, Node1 (deposit number 3)->　Node2 (6)->　Node3->　Node4->　Node1, then enter a location, such as 1, positioned to Node2, Node2 start at intervals of from three to delete a Node Node, until the end of the list to delete
