(1)有頭頭插單鏈表排序:
思路:遍歷比較原鍊錶,將最小的數取出插入新的鍊錶(按照尾插的順序插入)
#include #include typedef struct person
per;
per *head_list(per *one, int num) //有頭頭插
void show(per *head) //遍歷列印
while(head->next)
}per *sort(per *head) //排序
if(null == head->next->next)
per *min_pre = null;
per *new_list = null;
per *min = head->next; //因為是「 有頭」,指標指向 head->next
per *tmp = head->next;
per *tail_sort = null;
while(head->next)
tmp = tmp->next;
}if(min == head->next) //若最小的為第乙個
else
if(null == new_list) //按照尾插順序組成新鍊錶
else
}head->next = new_list; //遍歷比較完成,因為是有頭,則要給新組成的鍊錶的前面加個「 頭」
return new_list;
}int main()
show(&head);
printf("*****==after sort*****===\n");
sort(&head);
show(&head);
return 0;
}
(2)有頭尾插單鏈表排序
思路:遍歷比較原鍊錶,將最小的數取出插入新的鍊錶(按照頭插順序插入)
#include #include typedef struct person
per;
per *tail_list(per *one, int num) //尾插
one->next = temp;
return head;
}void show(per *head)
while(head->next)
}void *sort(per *head)
if(null == head->next->next)
per *min = head->next;
per *tmp = head->next;
per *new_list = null;
per *min_pre = null;
while(head->next)
tmp = tmp->next;
}if(min == head->next) //若第乙個就是最小
else
min->next = new_list;
new_list = min;
}head->next = new_list; //因為是有頭鍊錶,則要給新組成的鍊錶加個 「 頭」
return new_list;
}int main()
show(&head);
printf("*****===after sort*****====\n");
sort(&head);
show(&head);
return 0;
}
