The
best way to present this algorithm will be the game
High Low (which could be found at the TI95
calculator)

Think
of a number between 0 and 255 - it now my task to
guess this number by guessing a number and you must
tell me if the number is High or Low.

"Secret" number = 189

My
first guess = 128 => your answer
to Low (128 =
1000.0000_{2})

My next guess = 192 => your answer to
High (192 = 1100.0000_{2})

My next guess = 160 => your answer to
Low (160 = 1010.0000_{2})

My next guess = 176 => your answer to
Low (176 = 1011.0000_{2})

My next guess = 184 => your answer to
Low (184 = 1011.1000_{2})

My next guess = 188 => your answer to
Low (188 = 1011.1100_{2})

My next guess = 190 => your answer to
High (190 = 1011.1110_{2})

My last guess = 189 => your answer
to OK (189 =
1011.1101_{2})
