I can't seem to get this one!!
If I think of a number that is leass than 1000. Can you always guess it within no more than 10 guesses? When you guess, I will say either correct, answer is higher, or answer is lower. If you can always guess the answer tell how you would accomplish this.
Thanks for your time

There's at least a couple of ways to accomplish the feat. One is demonstrated by the Number Guessing game.

The other depends on your ability to approximately halve a range of numbers.

- "Is your number less than 500?"

- "No"
(The number is between 500 & 1000)

- "Is it less than 750?"

- "Yes"
(The number is between 500 & 750)

- "Is it less than 625?"

Etc.
