Top Three Treasures

The dragon's hoard is huge, but the museum only wants the three shiniest pieces. 💎

You get a list of at least three values. Print the three biggest, biggest first, comma-separated.

Example:

Input: values = [50, 12, 99, 34, 78] Output: 99,78,50

Sorting biggest-first gives [99, 78, 50, 34, 12] — the first three are 99, 78, 50.
