- In this programming exercise you will implement two functions. The first function will prompt the user for a file containing the number of vertices and entries of the adjacency matrix of a graph. It will return a two-dimensional list (a list of lists) containing the adjacency matrix.

- *IN C++ A handy feature of lists in Python is that you can use negative indices to get at elements starting from the very end. For example, x[-1] returns the last element in x, x[-2] returns the penultimate element, etc. Implement a struct named "PythonicIntVector" in the files "PythonicIntVector.h" and "PythonicIntVector.cpp" that supports the push_back and at methods of a vector of ints. However, be sure to add the functionality of negative indices. Don't forget that the at method still should throw exceptions for invalid indices (just like in Python)!) Write list comprehensions to generate the following:i) If numlist contains a list of numbers, create a new list that contains only thosenumbers that are less than 100. (e.g. [42, 130, 7, 100, 101] becomes [42, 7])ii) The numbers from 3 to 30 that are multiples of 3 (i.e. 3, 6, 9, 12, 15... 30)iii) The numbers from 3 to 30 that are multiples of both 3 and 2 (i.e. 6, 12, 18...)iv) If wordlist contains a list of strings, create a new list that has the words that startwith “p” or “P”. (e.g. [“Apple”, “pear”, “avocado”, “Pumpkin”] becomes[“pear”,”Pumpkin”] )Can you write this? Thanks!
