3. Which of the following is NOT a data structure in Standard Python library? А. Array B. List C. Dictionary D. Tuple 4. NumPy is able to save/load an array to/from a binary file in NumPy . What is the file extension of the output file with the method savez()? А. iрynb В. ру С. пру D. npz

What does the following python code do? f = open("sample.txt", "w") Choose all that apply.    Select 2 correct answer(s) a. writes "w" to the file called sample.txt  b. if the file sample.txt exists, deletes everything in it c. closes a file called sample.txt d. If the file called sample.txt exists, it writes at the bottom of the file e. opens a file called sample.txt for appending f. if the file sample.txt does not exist, it creates the file and opens it for writing g. reads the file called sample.txt starting from the top h. opens a file called sample.txt for reading

USING C++ PLEASE CREATE THREE FILES! IntCollection.h (or IntCollection.hpp): class definition IntCollection.cpp: class implementation main.cpp, including sample output and your answer to question 6 at the bottom. : main program to run the code The following code creates an IntCollection object named ‘c’. It adds seven integers to ‘c’, then uses a for loop to display the seven integers: int main() { IntCollection c; c.add(45); c.add(-210); c.add(77); c.add(2); c.add(-21); c.add(42); c.add(7); for (int i = 0; i < c.getSize(); i++) { cout << c.get(i) << endl; } } For this assignment you will add a copy constructor, a destructor, and three overloaded operators to the IntCollection class. In the design diagram below, the black member functions represent code that has already been implemented. You will be implementing the green items. Each item that you will be adding to the class is described below the diagram. private: int size // the number of ints currently stored in…
