Extremely Round
Description
Let's call a positive integer extremely round if it has only one non-zero digit. For example, $5000$, $4$, $1$, $10$, $200$ are extremely round integers; $42$, $13$, $666$, $77$, $101$ are not.
You are given an integer $n$. You have to calculate the number of extremely round integers $x$ such that $1 \le x \le n$.
The first line contains one integer $t$ ($1 \le t \le 10^4$) — the number of test cases.
Then, $t$ lines follow. The $i$-th of them contains one integer $n$ ($1 \le n \le 999999$) — the description of the $i$-th test case.
For each test case, print one integer — the number of extremely round integers $x$ such that $1 \le x \le n$.
Input
The first line contains one integer $t$ ($1 \le t \le 10^4$) — the number of test cases.
Then, $t$ lines follow. The $i$-th of them contains one integer $n$ ($1 \le n \le 999999$) — the description of the $i$-th test case.
Output
For each test case, print one integer — the number of extremely round integers $x$ such that $1 \le x \le n$.
