## dec2hex – Decimal do hexadecimal

Write a program that converts decimal numbers to hexadecimal, i.e., from base 10 to base 16. Input will consist of several lines each with a decimal number d of up to 9 decimal digits.

For each line of input, output should contain a line with the hexadecimal representation of the corresponding input number. The hexadecimal digits representing quantities from 0 to 15 should be: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f. Letters should be given in lowercase.

#### Example Input

``````10
16
12648430
2989
``````

#### Example Output

``````a
10
c0ffee
``````

### Scoring

• 1/6: works for the above example but produces output in an incorrect format
• 2/6: works for the above example and produces output in the correct format
• 5/6: works for other test cases
• 6/6: works for edge cases

### Hints

Remember the characters `'0'` through `'9'` are different than the numeric values `0` through `9`. You can create a function which converts between both by using an `if` or `case` expression.
