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.
