CF2040B.Paint a Strip
Paint a Strip
You have an array of zeros of length .
You can perform two types of operations on it:
- Choose an index such that and , and assign to ;
- Choose a pair of indices and such that , , , $a_l + \ldots + a_r \ge \lceil\frac{r - l + 1}{2}\rceil$, and assign to for all .
What is the minimum number of operations of the first type needed to make all elements of the array equal to one?
Input
Each test contains multiple test cases. The first line contains the number of test cases (). The description of the test cases follows.
The only line of each test case contains one integer () — the length of the array.
Note that there is no limit on the sum of over all test cases.
Output
For each test case, print one integer — the minimum number of needed operations of first type.
Note
In the first test case, you can perform an operation of the st type with .
In the second test case, you can perform the following sequence of operations:
- Operation of st type, . After performing this operation, the array will look like this: .
- Operation of st type, . After performing this operation, the array will look like this: .
The sequence of operations in the second test case 
In the third test case, you can perform the following sequence of operations:
- Operation of st type, . After performing this operation, the array will look like this: .
- Operation of st type, . After performing this operation, the array will look like this: .
- Operation of nd type, , . On this segment, , which is not less than . After performing this operation, the array will look like this: .
The sequence of operations in the third test case
