In this Kata we have to form sub strings of given length from the input string and output them separated by spaces. The first step which I took while solving this Kata was to initialize an empty string "ans" and then loop through the input string and add the sub string of required length to the ans string along with a space. We increment the index of loop by the same value as of the sub string length. 

If we reach a point where we don't have the sub string of length greater than the required length then we output whatever is left of the input string without any spaces.

In the end we output the "ans" as the solution to this Kata.
