Subtract or Divide
Description
Ridbit starts with an integer $n$.
In one move, he can perform one of the following operations:
- divide $n$ by one of its proper divisors, or
- subtract $1$ from $n$ if $n$ is greater than $1$.
A proper divisor is a divisor of a number, excluding itself. For example, $1$, $2$, $4$, $5$, and $10$ are proper divisors of $20$, but $20$ itself is not.
What is the minimum number of moves Ridbit is required to make to reduce $n$ to $1$?
The first line contains a single integer $t$ ($1 \leq t \leq 1000$) — the number of test cases.
The only line of each test case contains a single integer $n$ ($1 \leq n \leq 10^9$).
For each test case, output the minimum number of moves required to reduce $n$ to $1$.
Input
The first line contains a single integer $t$ ($1 \leq t \leq 1000$) — the number of test cases.
The only line of each test case contains a single integer $n$ ($1 \leq n \leq 10^9$).
Output
For each test case, output the minimum number of moves required to reduce $n$ to $1$.

Note
For the test cases in the example, $n$ may be reduced to $1$ using the following operations in sequence
$1$
$2 \xrightarrow{} 1$
$3 \xrightarrow{} 2 \xrightarrow{} 1$
$4 \xrightarrow{} 2 \xrightarrow{} 1$
$6 \xrightarrow{} 2 \xrightarrow{} 1$
$9 \xrightarrow{} 3 \xrightarrow{} 2\xrightarrow{} 1$
