Just like the problem ASCII 1, this short description problem is intended to review basic concepts, encourage you to read about new languages and is a score length based problem that can put the usual rank upside down. You just have to print the first char of a given input.

Input

One string, whose length is not longer than 100 characters, of printable and non-printable characters (i.e., 1 <= ASCII code <= 126).

Output

The first, and just the first, character of the string.

Score

Source length.

Example

Input:
a

Output 
a

Input:

Output 
F

Input:
The quick brown fox jumps over the lazy dog.

Output 
T
