Please write a PYTHON function program that takes a list of integers and returns the same list, but without any duplicates

I am learning C for a class I am taking and a homework assignment asks us to makes a list of integers, divides the list into a number of segments, and displays each segment in reverse order. We need to use the function malloc to dynamically allocate locations for variables a and b. The full assignment is below. I am not too familiar with C and I don't know how to split the list into two arrays.

PYTHON Problem Statement Given a list of numbers (nums), for each element in nums, calculate how many numbers in the list are smaller than it. Write a function that does the calculation and returns the result (as a list). For example, if you are given [6,5,4,8], your function should return [2, 1, 0, 3] because there are two numbers less than 6, one number less than 5, zero numbers less than 4, and three numbers less than 8. Sample Input smaller_than_current([6,5,4,8]) Sample Output [2, 1, 0, 3]

Write a C++ Program that does the following: Implement a sort function using a vector.Ask the user to enter numbers to be sorted. Add them to the vector. The user will signal the end of input bygiving you a negative number.Then, sort the vector. Because this is a vector, you don’t need to pass the number of entriesin the vector.Then, print out the vector in order.Remember the following things about vectors.a) You declare a vector v of ints by saying vector⟨int⟩ v;b) You add elements to a vector by saying v.push back(thing to be added);c) You access elements of a vector with [ ] just like an array;d) One of the vector member functions is .length()

In C++ please and thank you!

Write a C++ program that reads a list of numbers from a file into an array, then uses that array to find the average of all the numbers, the average of the positive and negative numbers (0 is neither positive nor negative!), and the largest number. The point is to be able to store data in an array and do things with it Your program must contain at least the following four functions... read_list() This function will take as input parameters an array of integers and a string filename. It will open that file and read in numbers, storing them in the array, stopping at the end of the file. Remember that there are tricky issues with extra whitespace at the end of the file. You can assume the file contains only integers. The function will return the number of numbers that were read in.Note: In versions of Visual C++ pre-2010, when using the open function with a string argument, you must call the c_str() function on the string variable, such as:my_input_stream.open( filename.c_str() ) 2.…

In C++ Create an array of head pointers, statically allocated of size 101 of that type: Now, create a pointer that can point to the first element: Show how to dynamically allocate an array of 101 elements of head pointers: Write the code to initialize each element to NULL: Rewrite the code to initialize each element to NULL using pointer arithmetic:
