Question

Problem: In this problem, we would like to implement the algorithm to calculate digit sum of a given natural number that can be used in detecting errors in message transmission or data storage.
For example:
N = 103509, the digit sum = 1 + 0 + 3 + 5 + 0 + 9 = 18.
N = 9512, the digit sum = 9 + 5 + 1 + 2 = 17
Exercise 1:

  • Write a pseudo-code to solve the above problem using Iteration.
  • Write a program from the pseudo-code and solve the Problem using Iteration.
  • Calculate the complexity. Justify your answer.

Exercise 2:

  • Write a program to solve the Problem using Recursion (with Iteration if necessary).
  • Calculate the complexity. Justify your answer.

Exercise 3:

  • Write a program to solve the Problem using a List data structure.

Note: Elements in List data structure can be used to store a digit of the given natural number.
