Difference between “set” and “multiset”

set multiset
A “set” belongs to an associative container which holds a group of unique values A “multiset” is an associative container which holds the duplicate elements.
It should not have the same value for two elements. It is possible to have two elements which have same values.
In order to use “set” class, the header file “#include<set>” should be included in the program. In order to use “multiset” class, the header file “#include<set>” should be included in the program.
Some of the member function in set class are “begin()”, “clear()”, “empty()”, “end()”...

Sets store their elements in an unordered fashion.True or False

get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary.

get_movie_dict() takes a 2-D list similar to movie_db and a dictionary similar to ratings as the parameters and returns a dictionary, where each {key: value} of this dictionary is {a valid movie id: a list containing the name of the movie, the year it got released, and the average rating of this movie}. I will refer to this dictionary as movies.>>> movies = get_movie_dict(movies_db, ratings)>>> display_dict(movies)1: ['Toy Story', 1995, 3.92]2: ['Jumanji', 1995, 3.43]3: ['Grumpier Old Men', 1995, 3.26]4: ['Waiting to Exhale', 1995, 2.36]5: ['Father of the Bride Part II', 1995, 3.07]6: ['Heat', 1995, 3.95]7: ['Sabrina', 1995, 3.19]8: ['Tom and Huck', 1995, 2.88]9: ['Sudden Death', 1995, 3.12]10: ['GoldenEye', 1995, 3.5]11: ['American President The', 1995, 3.67]12: ['Dracula: Dead and Loving It', 1995, 2.42]13: ['Balto', 1995, 3.12]14: ['Nixon', 1995, 3.83]15: ['Cutthroat Island', 1995, 3.0]16: ['Casino', 1995, 3.93]17: ['Sense and Sensibility', 1995, 3.78]18: ['Four…
