The following problems below require the utilization of recursion to be solved. Must add comments. Write a python program that compute the sum of non-negative integers from an input 10-element list with odd indices are negative values and even (including 0) indices are non-negative values.

Write a Python recursive sum function that can sum the content of a list, tuple, set, and dictionary. Do no use any built-in function!!!! thank you, IN PYTHON!!!

The language is in Racket. Please answer the question in the screenshot.

Write a Python source code using recursion to merge two sorted lists into a merged list which is obviously a bigger list containing all elements from the two sorted lists. Comment on the computational complexity of this code. Please name your function "merge" that has two arguments (first list, second list) and return a list of int.
