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 `0`s if necessary. ## Constraints * $0 \leq N \leq 255$ * $N$ is an integer. ## Input The input is given from Standard Input in the following format: $N$ [samples] ## Notes The judge is case-sensitive. Specifically, you **cannot** use `abcdef` as hexadecimal digits instead of `ABCDEF`.

Samples

Input #1

Output #1

63

$99$ is represented as `63` in hexadecimal.

Input #2

Output #2

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`.

Input #3

Output #3

Input #4

Output #4

FF
