Here we are, the final challenge!
How to solve Turing puzzle #6:
In the top line, choose the "if" command with a 0 and then make the second yellow symbol a 0.
Down below, make the first yellow symbol into a 1 and then select the "if" command with a 1.
Hit green arrow and you're done! Well, almost. Google will run through all of your previous answers and then bring you to a search page full of Alan Turing results. From there, if you click the Google icon in the top-left corner, you'll return to the Google home page. Click the green arrow again, and Google will bring up a whole new set of puzzles. Warning: They are a lot harder.
Happy number crunching.
