Hey, first of all thanks for the series. Secondly I just had a quick math question, wouldnt (left + right) / 2 suffice? why did you say "just to be accurate" with the equation you used. Maybe i'm just too tired and its going over my head at the moment lol

can anyone tell me why he use (right-left)/2 instead of right to calculate mid point?

isnt this infinite loop if key not in array?

so what happens if the length of the array is even? if the right most index is 5, and the beginning index is 0, (0+5)/2 is a fraction. How do you take the index of a fraction?
