Converting to Hexadecimal

Timelimit: 1
Data stored in computers are in binary. An economic way of visualizing these numbers is the usage of base 16 (hexadecimal).
Your task is to write a program that, given a natural number at base 10, shows its representation in hexadecimal.
Input
The input is a positive integer number V at base 10 (1 ≤ V ≤ 2 x 109).
Output
The output is the same number V at base 16 in a single line (don't forget the end-of-line character). Use uppercase letters, as shown in the examples.
