Question 5: 2.1 Sum Problem View Past Answers Given a positive number n, the sum of all digits is obtained by adding the digit one-by-one. For example, the sum of 52634 is 5+2+6+3+4 = 20. Write a recursive and iterative function sum(n) to compute the sum of all the digits in n. You may assume that n > 0. template.py 1- def sum R(n): if len(str(n)) == 1: return n else: return 20 7. def sum I(n): add = 0 while n: add += n % 10 8 9- 10 n //= 10 return add 11 12

1. Number Sorter in Matlab  Requirements: ●      Must be a console program ●      Reads integers from standard input (i.e from the user via the keyboard) until a number less than or equal to zero is input. This indicates the end of input. ●      Once end of input is detected, the program sorts all of the numbers in ascending order and displays them ●      You can choose any sort algorithms. For instance: ○      choose a random input, n, not yet sorted in the list of input values ○      go through the list of input values and place all values less than n to the left of n and all other values to the right of n ○      Once this is done then n is sorted, so go back and repeat the first step ○      Once all values n are sorted the entire list is sorted ●      You are not allowed the built-in function sort in Matlab to solve this problem 2) In 200 explain how the program function.    Note : manually solve the vector using any algorithm but don't use the built-in function  "sort " in matlab…
