In the ideal scenario, what is the minimum amount of tries before you can be 100% the answer is correct?

yeah I'd agree with both those

ibavly has the quickest possible solution and eyebooger has the quickest possible solution using the optimal strategy

Easy problem but one I liked

A and B represent digits

A/B=A6/6B=A66/66B=A666/666B=A6666/6666B

What are the possible A and B combos?

Is there an easy way to solve that besides trial and error?

It is simple to show that B < 7. 6 is obvious, then the other options are easy to check. I think it is also not too hard to show that exactly one of them must be even when not both 6.

What is the fastest way to fill up a text editor with a string of 1 million of the same character? (Let’s go with the letter “i”.)

There are a lot of variables here. You can type “i’s” at a certain rate, maybe around five per second, by simply pressing its key repeatedly. You can also hold down the key, initially getting a single “i,” and then after a “repeat delay” of about half a second, getting a quickly repeating stream of “i’s” at a “repeat rate” of about 30 per second. You can also use copy and paste. If you release the “i” key, you can hit Ctrl+A then Ctrl+C, then hit the right arrow key, and finally Ctrl+V, selecting all your text, copying it and pasting it to what you had already. (Replace Ctrl with Command if on a Mac, of course.) This process costs you about a second from “i” key release to initial depress of Ctrl+V. If you hold down Ctrl+V, there is the same repeat delay and repeat rate that then generates a bunch of copies of your clipboard very quickly.

So the questions are: How big should you make the original edition of your clipboard before you transition to the more efficient copy/paste? Then, how long should you stick with that clipboard before going back to the Ctrl+A and growing your clipboard again?

If we're assuming that our only parameters are how many original 'i's we have, and how often we repeat the ctrl+a, the best I get it starting with 12 'i's and hitting ctrl+a every 16 pastes.

12 'i's = .866s
paste 16 times = 2s

need to repeat 4 times - 12*17^4 = 1002252

4*2+.866 = 8.866s

Sort of surprised that it can get this fast. Not at all optimized though, I guess you could shave some milliseconds if you're willing to use an inconsistent number of pastes each time.

Pasting 16 times takes 16/30 seconds not 15/30 seconds. So you're either pasting 15 times for a size of 16 in 2s or 16 times for a size of 17 in 2.03s I think.

Best I can get is 9.008s with an initial paste of 'I'+ 15x 'I' and then repeat every 15.

I dunno.

it's 15/30 because you click right for one copy (included in the 1 second) and then the first ctrl+v is instantaneous, so after the .5s delay you get another 15 copies in .5s for 17 total copies.
