题目描述

We call a string as a 0689-string if this string only consists of digits 0, 6, 8 and 9. Given a 0689-string $s$ of length $n$, one $\textbf{must}$ do the following operation exactly once: select a non-empty substring of $s$ and rotate it 180 degrees.

More formally, let $s_i$ be the $i$-th character in string $s$. After rotating the substring starting from $s_l$ and ending at $s_r$ 180 degrees ($1 \le l \le r \le n$), string $s$ will become string $t$ of length $n$ extracted from the following equation, where $t_i$ indicates the $i$-th character in string $t$:

$$t_i = \begin{cases} s_i & \text{if } 1 \le i < l \text{ or } r < i \le n \\ \text{`0'} & \text{if } l \le i \le r \text{ and } s_{l+r-i} = \text{`0'} \\ \text{`6'} & \text{if } l \le i \le r \text{ and } s_{l+r-i} = \text{`9'} \\ \text{`8'} & \text{if } l \le i \le r \text{ and } s_{l+r-i} = \text{`8'} \\ \text{`9'} & \text{if } l \le i \le r \text{ and } s_{l+r-i} = \text{`6'} \\ \end{cases}$$

What's the number of different strings one can get after the operation?

输入格式

There are multiple test cases. The first line of the input contains an integer $T$, indicating the number of test cases. For each test case:

The first and only line contains a 0689-string $s$ ($1 \le |s| \le 10^6$).

It's guaranteed that the sum of $|s|$ of all test cases will not exceed $10^7$.

输出格式

For each test case output one line containing one integer, indicating the number of different strings one can get after applying the operation exactly once.

提示

We hereby explain the first sample test case.

$$\begin{array}{|c|c||c|c|}\hline \textbf{Substring} & \textbf{Result} & \textbf{Substring} & \textbf{Result} \\ \hline 0 & 0689 & 68 & 0899 \\ \hline 6 & 0989 & 89 & 0668 \\ \hline 8 & 0689 & 068 & 8909 \\ \hline 9 & 0686 & 689 & 0689 \\ \hline 06 & 9089 & 0689 & 6890 \\ \hline \end{array} $$

It's easy to discover that we can get $8$ different strings after the operation.
