Consider increasing the number range 0-1000 and add random tests to prevent cheating.

Nothing changed, same error as yesterday;-)...

Thanks for the feedback! Should be fixed now.

I think your testcases are wrong, look here (count 6 tries):

Guess: 23
1. 0, 100, Is it 50 ?
2. 0, 50, Is it 25 ?
3. 0, 25, Is it 12 ?
4. 12, 25, Is it 18 ?
5. 18, 25, Is it 21 ?
6. 21, 25, Is it 23 ?  => Yes
expected:<7> but was:<6>
