Write this using a java script function and test  with  a mocha or postman to see if it passes the test

IN JAVA Write a function that takes in user input as a string. For all characters which are numeric, double its value and, if it is two digits, then replace it with the sum of its digits (e.g., 6 → 12 → 3 whereas 3 → 6). For all characters which are in uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with uppercase (e.g., m → M and N → n).  The program should keep asking the user to enter strings until they either enter ‘q’ or ‘Q’.

The Python print function supports other keyword parameters besidesend. One of these other keyword parameters is sep. What do you thinkthe sep parameter does? Hint: sep is short for separator. Test your ideaeither by trying it interactively or by consulting the Python documentation.

In Python language, define a function that takes two parameters count and sum as the parameters and returns the average from the function. Also, make a call to the function for some sample test cases.
