题目描述
On March 14, the day of the number $\pi$ is celebrated all over the world. This is a very important mathematical constant equal to the ratio of the circumference of a circle to its diameter.
Polycarp was told at school that the number $\pi$ is irrational, therefore it has an infinite number of digits in decimal notation. He wanted to prepare for the Day of the number $\pi$ by memorizing this number as accurately as possible.
Polycarp wrote out all the digits that he managed to remember. For example, if Polycarp remembered $\pi$ as $3.1415$ , he wrote out 31415.
Polycarp was in a hurry and could have made a mistake, so you decided to check how many first digits of the number $\pi$ Polycarp actually remembers correctly.

输入格式
The first line of the input data contains the single integer $t$ ( $1 \le t \le 10^3$ ) — the number of test cases in the test.
Each test case is described by a single string of digits $n$ , which was written out by Polycarp.
The string $n$ contains up to $30$ digits.
