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.


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
