1.In a loop, fill an array for up to 50 even numbers and a set for up to 50 odd numbers. Use the merge() algorithm to merge these containers into a vector. Display the vector contents to show that all went well. 2. Write a program that copies a source file of integers to a destination file, using stream iterators. The user should supply both source and destination filenames to the program. You can use a while loop approach and a list container with integer data type. Within the loop, read each integer value from the input iterator and add the value to the list container by using push_back() function, then increment the input iterator.Finally, use an output iterator to write the list to the destination file

Create class Test in a file named Test.java. This class contains a main program that performs the following actions: Instantiate a doubly linked list. Insert strings “a”, “b”, and “c” at the head of the list using three Insert() operations. The state of the list is now [“c”, “b”, “a”]. Set the current element to the second-to-last element with a call to Tail() followed by a call to Previous()Then insert string “d”. The state of the list is now [“c”, “d”, “b”, “a”]. Set the current element to past-the-end with a call to Tail() followed by a call to Next(). Then insert string “e”. The state of the list is now [“c”, “d”, “b”, “a”, “e”] . Print the list with a call to Print() and verify that the state of the list is correct.

python exercise: Write a Python function called calculate_average that takes a list of numbers as input and returns the average of the numbers in the list. If the input list is empty, the function should raise an EmptyListError exception. Handle the case where the input list is empty by raising a custom EmptyListError exception. This exception should have an error message that says "Cannot calculate average of an empty list".

Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py  Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list:     [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as:     ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”.  In this small example, we don’t achieve much of a savings (and indeed the…

45- Which of the following statements about lists in Python is true? a. Items within a list are unordered. b. A list can grow in size as items are added to it. c. All items in a list must have the same type. d. Items within a list must be unique. e. Items can only be added to a list by creating a new list object. f. Lists can only contain items which have a primitive type.

Implement the following function using C++ remove_redundant() This method will clear out the duplicate numbers in your linked list. It is also imperative that you will use an instance of this Linked List class to hold the numbers that you have already checked and use the methods in this instance. In the example 10 -> 10 -> 20 -> 30 -> 10, calling remove_redundant() will remove the other 2 10's that occurred later, hereby making the list 10 -> 20 -> 30. Limitation: You cannot have a nested loop here nor use methods that employ loops as the performance of our linked list will suffer.

Python  function getData(fname:str)->ndarray that inputs data from a file into a list, then converts the list to a NumPy array of integer values and returns the array. The text file (fname) contains: integer numbers, one per line numbers are in the range 0 <= n <= 99 r * c (rows * columns) quantity of numbers, where c = r + 1 Example:  15 22 65 4 78 91 7 35 60 16 99 12 == [[15 22 65 4]  [78 91 7 35]  [60 16 99 12]]

A. Create function getData(fname:str)->ndarray that inputs data from a file into a list, then converts the list to a NumPy array of integer values and returns the array. The text file (fname) contains: integer numbers, one per line numbers are in the range 0 <= n <= 99 r * c (rows * columns) quantity of numbers, where c = r + 1.   Sample follows: 15 22 65 4 78 91 7 35 60 16 99 12   The function will convert the list of numbers into a 2-dimensional NumPy array with r rows and c columns. Sample follows: [[15 22 65 4]  [78 91 7 35]  [60 16 99 12]]   B. Create a function getSum(arr:ndarray)->int that returns the sum of all the elements within a 2-dimensional array. C. For the array example above, a sum of 504 is returned by getSum(arr). D. The mathematical functions available for NumPy arrays may not be used. Determine the sum by iterating over all the elements of the array.

The function last_words in python takes one parameter, fname, the name of a text file, and returns a list containing the last word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["red", "yellow", "green"] should be returned. NOTE: You may assume the file will contain no blank lines. BIG HINT: If line is a string representing a line of text (inside a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = last_words("wordlist1.txt") print(L) ['happy', 'sad', 'angsty', 'euphoric', 'maudlin']

In Python please:  7.9 LAB: Sorting TV Shows (dictionaries and lists)   Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt. Ex: If the input is: file1.txt and the contents of file1.txt are: 20 Gunsmoke 30 The Simpsons 10 Will & Grace 14 Dallas 20 Law & Order 12 Murder, She Wrote the file…

C++ The People class holds an unsorted list of humans. Initially, this list is empty. Upon inserting a Human object, it is added to the array at the next available position and the position value in incremented. If the position value is equal to the size value, do not insert the Human. Instead, throw an exception that your driver can catch to print an error that the People object is full.   Create a People class with the following features: Each People object has a statically allocated array of Human objects. Size attribute representing the maximum size of the array. Position attribute representing the next free position in the array. Default constructor with no arguments. Search method that takes a string argument and returns a Human object. This method returns the first Human object with a name matching the string argument. In other words, pass the name of a Human as a string, search the list of humans for one with that name. If found, return this human. Else throw an…

In C++   Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list.  In addition, you should have a private data member that specifies the length of the list.  Create a constructor that takes a file name as parameter, and fills up the list with lines from the file.  Make sure that you set the dynamic array to expand large enough to hold all the lines from the file.  Also, create a constructor that takes an integer parameter that sets the size of an empty list.   Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!

Word FrequencyWrite a python program that reads the contents of a text file. The program should create a dictio-nary inwhich the keys are the individual words found in the file and the values are the number of timeseach word appears. For example, if the word “the” appears 128 times, the dictionary wouldcontain an element with 'the' as the key and 128 as the value. The program should eitherdisplay the frequency of each word or create a second file containing a list of each word and itsfrequency.
