A program to demonstrate doubly linked list using pointers – insert (beginning, end, middle), delete(beginning, end, middle),view) is:
/* Initialize nodes */
struct node *head;
struct node *one = NULL;
struct node *two = NULL;
struct node *three = NULL;
/* Allocate memory */
one = malloc(sizeof(struct node));
two = malloc(sizeof(struct node));
three = malloc(sizeof(struct node));
/* Assign data values */
one->data = 1;
two->data = 2;
three->data = 3;
/* Connect nodes */
one->next = two;
one->prev = NULL;
two->next = three;
two->prev = one;
three->next = NULL;
three->prev = two;
/* Save address of first node in head */
head = one;
What is a Doubly Linked List?This refers to the linked data structure that contains of a set of sequentially linked records called nodes.
The requested program is given above.

In python please:
Assume the variable definitions references a dictionary. Write an ig statement that determined whether the key ‘marsupial’ exist in the dictionary. If so, delete ‘marsupial’ and it’s associated value. If the key is not the dictionary, display a message indicating so.
Answer:
"
if 'marsupial' in dictionary:
del dictionary['marsupial']
else:
print("The key marsupial is not in the dictionary")
"
Explanation:
So you can use the keyword "in" to check if a certain key exists.
So the following code:
"
if key in object:
# some code
"
will only run if the value of "key" is a key in the object dictionary.
So using this, we can check if the string "marsupial' exists in the dictionary.
"
if 'marsupial' in dictionary:
# code
"
Since you never gave the variable name for the variable that references a dictionary, I'm just going to use the variable name "dictionary"
Anyways, to delete a key, there are two methods.
"
del dictionary[key]
dictionary.pop(key)
"
Both will raise the error "KeyError" if the key doesn't exist in the dictionary, although there is method with pop that causes an error to not be raised, but that isn[t necessary in this case, since you're using the if statement to check if it's in the dictionary first.
So I'll just use del dictionary[key] method here
"
if 'marsupial' in dictionary:
del dictionary['marsupial']
else:
print("The key marsupial is not in the dictionary")
"
The last part which I just added in the code is just an else statement which will only run if the key 'marsupial' is not in the dictionary.

Why is assembly language better than other kinds of high level?It implies means that the programs that one uses to write via the use of high-level languages can be run easily on any processor that is known to be independent of its type.
Note that it is one that has a lot of better accuracy and an assembly language is one that carries out a lot of better functions than any high-level language, in all.
Note also that the advantages of assembly language over high-level language is in terms of its Performance and accuracy as it is better than high-level language.
Hence, The special reason why assembler language is preferred to high level language is that It is said to be memory efficient and it is one that requires less memory.
