Types of Linked List

A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.

Linked List

When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).

Question

I need to create the functions for both union and merge Linked List.

Union Linked Lists
Assume two linked lists that represent Set A and Set B respectively. Implement the following function to obtain
their union A U B and return the result as a new linked list. Note that a Set should not contain duplicate elements
(e.g., integers), but its elements are not assumed to be sorted in the list. The definition of the function
unionLinkedList is as the following:
Linked List unionLinked List (const Linked List& LA, const LinkedList& LB)
For example, if
LA = (3, 5, 8, 11)
LB = (2, 6, 8, 9, 22, 24)
Then unionLinked List(LA, LB) = (3, 5, 8, 11, 2, 6, 9, 22, 24). Note the list isn't sorted. To compute the
union operation, you need to implement the Linked List search function to check whether a value is in the list or
not.

Merge Linked Lists
Assume two input linked lists, LA and LB, whose elements are both in the non-descending order (duplicates may
exist). Implement the following function to merge LA and LB into a new linked list (as the return value). The
elements in the new list should still be in the non-descending order. The definition of the function
mergeLinked List is as the following:
Linked List mergeLinked List (const LinkedList& LA, const Linked List& LB);
For example, if
LA = (3, 5, 8, 11)
LB = (2, 6, 8, 9, 22, 24)
Then mergeLinkedList (LA, LB) = (2, 3, 5, 6, 8, 8, 9, 11, 22, 24). Note same values may repeat

Problem 4 (Merging Dictionaries Again) Write a function called merge2(d2, d2) that takes two dictionaries as input parameters. This function will create a new dictionary that contains everything from the two input dictionaries and return it. The same key might appear in both input dictionaries. In the output dictionary, the value for each key will be a list that has all values corresponding to this key in the two input dictionaries. Sample run, >>> d1 = {'a': 100, 'b': 200, 'c':300} >>> d2 = {'a': 300, 'b': 200, 'd':400} >>> d3 = merge2(d1,d2) >>> display(d3) a, [100,300] b, [200,200] c, [300] d, [400]

Please written by computer source 16 In this lab, you need to implement a simple linked list using dynamic memory allocation. The structure of node in the linked list has been declared in “lab3.h”. Also, the functions of linked list have been declared in “lab3.h” as well. In “main.c”, these functions are called. Your work is to finish these function implementations in a separate C source file, and create a makefile which can compile your separate C source file along with “main.c” and “lab3.h”. You can follow the comments in “main.c” and “lab3.h” to finish this lab. Please do not change “main.c” and “lab3.h”, because your separate C source file will be compiled with these two files posted on BlackBoard. When you test your program, please put “main.c”, “lab3.h”, your separate C source file and your makefile in the same directory and compile.

What description to Array and Linked List is mistake? O a. Using Linked list, if there is a existed data will be removed, it needs only to move the links of data node and doesn't need to change the location of data saved. O b. Using Linked list, if there is a new data will be increased, it needs only to move the links of data node and doesn't need to change the location of data saved. O c. If the size of main memory is enough, there is no upper bound limitation to increase new data when Linked list is used. O d. For limited number of data, Array is allocated less memory size, because all sequential data are allocated into continuously space. O e. Using Array, if there is a new data will be increased, it needs to move some existed data to new location to free the suitable location new data because the sequential order should be kept. O f. If the size of main memory is enough, there is no upper bound limitation to increase new data when Array is used. O g. The operations on Array is…
