Problem:

First Digit of an Integer.

We already saw how to find the last digit of a number. Let's proceed ahead with finding the first digit. Given a four-digit number N, find its first digit. There will be no leading zeros in the integer N.

Input:

The first line contains an integer T denoting the number of test cases.

Each test case contains one integer N.

Output:

For each test case on a new line, print the first digit of N.

Constraints:

• 1<=T<=10

• 1000<=N<10000

Example Input:

2

1234

4567

Example Output:

1

4
