Coding Kata’s

A useful tool for learning a new language or exploring ideas like TDD is to use code Kata’s. A Code Kata is a small, reasonably simple problem. Here are a few example code Kata’s I have used.

CalcStats

Your task is to process a sequence of integer numbers to determine the following statistics:

• Minimum value
• Maximum value
• number of elements in the sequence
• average value
• Sum of all values
• Is the total sum an odd or even number

Try using a technology you are not familiar with and bonus Kudos for using TDD

Roman Numerals

Write a function that converts an integer (up to a max value of 3,999) into Roman numerals

1I = 1
2V = 5
3X = 10
4L = 50
5C = 100
6D = 500
7M = 1000

3999 = MMMCMXCIX

Optional Task #2

Write a function that converts Roman numeral strings back to their integer value
