About a more intuitive linked list representation method

[张铂坤]

Hello，I‘m new in gsoc,I have a idea for dart.

it's about linked list，I will Upload some files to explain the idea more visually.

I am a user of C++, and creating linked lists troubles me, so I thought of a more superficial way to create linked lists.

I want to use the following way to create：

This is the expected way to create a singly linked list：
|HEAD|ptr1->| |something1|ptr2->| |something2|...->| |the last|ptr3->||NULL|

This is the expected way to create a singly linked list.

|HEAD| is the Head of singly linked list，|ptr1->|is the pointer points to the next bit in the linked list,The complete status of a block in the linked list is |something1|ptr2->|.

and This is the expected way to create a doubly linked list.

|HEAD|ptr1->| |<-PTR1|something1|ptr2->| |<-PTR2|something2|...->| |<-PTRn||the last|ptr3->||NULL|

|<-PTR1|something1|ptr2->| 

Two pointers are declared to link the two blocks ,The rest is similar to a singly linked list.

More detailed representation

These are rough ideas, unfortunately I don't have enough knowledge to implement it, so I think this is the best place to express it.
