6 5 鏈式表操作集

本題要求實現鏈式表的操作集。

position find

( list l, elementtype x )
;list insert
( list l, elementtype x, position p )
;list delete
( list l, position p )
;

typedef

struct lnode *ptrtolnode;
struct lnode 
;typedef ptrtolnode position;
typedef ptrtolnode list;

position find( list l, elementtype x )：返回線性表中首次出現x的位置。若找不到則返回error；

list insert( list l, elementtype x, position p )：將x插入在位置p指向的結點之前，返回鍊錶的表頭。如果引數p指向非法位置，則列印「wrong position for insertion」，返回error；

list delete( list l, position p )：將位置p的元素刪除並返回鍊錶的表頭。若引數p指向非法位置，則列印「wrong position for deletion」並返回error。
