ADV04J - Invisible point

no tags 

Daniel marked a point on a plane with sympathetic ink and he has also drawn a regular n-gon with normal ink. Max can see the n-gon, but can't see the point. Max can draw a line and ask Daniel which side of the line the point is. What is the minimum number of questions Max have to ask to define if the point is inside the n-gon in the worst case?


First line of the input contains number t - the amount of test cases. Each test consists of the single integer n - the amount of sides of the n-gon.


1 <= t <= 100
3 <= n <= 1000000


For each test case print a single number - the answer to the question in the statement.

If Im not wrong, test case 4 (a rectangular); draw diagonally to find which side the point is. And then, we can draw the next 2 lines based on side the point is, to get the answer (the point inside the n-gon or not).
