$7.$ Add the Last If Statement

The last step in implementing the function is to handle the variable $\text{'}$y$.$ Note that $$y$$ only counts if it is not at the start of the word. How do you check that? It is not enough to look for the first $$y$$ and ignore it if it occurs at the start. What if the $$y$$ occurs twice? Look at the functions in introcs, paying attention to the optional arguments, for an idea on how to approach this.
