A school ranks quiz scores. The top score gets gold, and the **second largest distinct** score gets silver. Two students with the same score share one rank, so 9 9 7 has gold 9 and silver 7.
Read the scores and print the second largest distinct value. If fewer than two distinct values exist, print none.
Constraints: 1 <= n <= 2000, each score is between -1000 and 1000.
Input. First line n. Second line n integers separated by spaces.
Output. One integer, or the word none.
