Created by Yaz Majeed

Solve Later

x is a vector of undetermined length

You are to replace every 3rd element with the number 4, example:

x = [11 23 34 43 2 31 6 34 5 45 26 7 78];

output = [11 23 4 43 2 4 6 34 4 45 26 4 78];

Make sure the code accounts for varying vector lengths

In view of the recent spate of trivial problems with no test suite to speak of, thanks for making the effort of providing a proper test suite and a slightly less trivial problem.
