Secret Santa Configuration

Given the number of participants n for a Secret Santa event, determine whether a valid configuration exists. A valid configuration requires that n \ge 2 (i.e., there must be at least two participants).

If the condition is met, output "Yes"; otherwise, output "No".

Constraints: 1 \le n \le 1000.

inputFormat

Input consists of a single integer n representing the number of participants. This integer is provided via standard input.

outputFormat

Output a single line containing "Yes" if a valid Secret Santa configuration exists (i.e. if n \ge 2) or "No" otherwise. The output should be written to standard output.
