Coding Puzzle#1 - Generic Random Status Filler

Level: Intermediate-Advance

Topic: Plain Loops

Who Wins: One who accomplishes this task with least number of iterations

Short Description: Create a method such that it is capable of populating enum property all objects in a list with random values based on pre-defined ratio

Puzzle Details:

Let’s say I’ve a following enum and a class:

public enum TASK_STATUS

    {

        ToBeStarted,

        InProgress,

        Completed

    }

    public class TodoTask

    {

        public int Id { get; set; }

        public string Comment { get; set; }

        public TASK_STATUS Status { get; set; }

    }

I want to create 50 TodoTask fake instances and add it to a list List<TodoTask>(). However, I want status values to be randomly set. For example, out of 50 values,

25 should be randomly set as InProgress,

15 should be randomly set as Completed and

10 should be randomly set as ToBeStarted

Now, I need a generic method method such that I can use that method to accomplish above. I.e., method should be such that I can specify my list and ratio of enum values I want and populates the list accordingly.

Note, it should be generic as my list of  ratios may change in future or I may want to use to fill other enums. 

Tricky Part – How do you design signature of method to make it generic and also how do you manage desired ratio

Think you are a champ in loops... ahm ahm.. let's see if you get it done better and faster  :)

This is one of the approach to solve it. This is the best I could come up so far. DOWNLOAD
Number of iterations involved is roughly: Number of items in list + Number of enum values + (Number of enum values -1). Thats it!
