You are writing a new revolutionary archiver. The archive is essentially a
pair of non-decreasing sequences of integers of equal length **K**:
**0≤x1≤...≤xk** and **0≤y1≤...≤yk**.
The decompression algorithm proceeds as follows:
1. Sequence **(0,0), (x1,y1), ... (xk,yk), (xk, 0), (0, 0)** defines a polygon **P**
2. Starting from the point **(0,0)**, increase either **x** or **y** coordinate by 1 without moving outside of **P**. If both moves are available, you should increase y. After each step write **0** to output if incremented **x** or **1** otherwise.
3. Repeat step 2 until you end up in point **(xk,yk)**.
Example: decompression of sequence **(3,4), (7,6), (7,8)** will produce string
**010101100100111**.
Your task is to write a compression rate calculator, that is given binary
string s find the smallest value of **K** for which there exists archive that
decompresses to s.
## Input
The first line contains a single integer **T**, **T** ≤ 20. **T** test cases
follow, where each test case consists of one binary string with length **≤
1,000,000**.
## Output
Output a single line containing the smallest possible **K**.
