Problem Statement

In the hexadecimal system, where the digits ABCDEF corresponding to $10,11,12,13,14$, and $15$ are used in addition to 0123456789, every integer between $0$ and $255$ is represented as a $1$- or $2$-digit numeral.
For example, $0$ and $12$ are represented as $1$-digit hexadecimal numerals 0 and C; $99$ and $255$ are represented as $2$-digit hexadecimals 63 and FF.

Given an integer $N$ between $0$ and $255$, convert it to an exactly two-digit hexadecimal numeral, prepending leading 0s if necessary.

Notes

The judge is case-sensitive. Specifically, you cannot use abcdef as hexadecimal digits instead of ABCDEF.

Constraints

• $0 \leq N \leq 255$
• $N$ is an integer.

Input

The input is given from Standard Input in the following format:

$N$

Output

Print the answer.

99

63

$99$ is represented as 63 in hexadecimal.

12

0C

$12$ is represented as C in hexadecimal.
Since we ask you to convert it to a two-digit hexadecimal numeral, the answer is 0C, where 0 is prepended to C.

0

00

255

FF
