Validate Security PIN

You are given a security PIN and an integer N. Your task is to validate the PIN based on the following criteria:

• The PIN must be exactly N digits long.
• The PIN can only contain numeric digits (0-9).
• The PIN must contain at least one even digit. In other words, there must exist a digit d such that \(d \mod 2 = 0\).
• The PIN must not contain any repeating digits; each digit must be unique.

If the PIN meets all the criteria, output True; otherwise, output False.

inputFormat

The input is read from standard input (stdin) and consists of two lines:

1. The first line contains a single integer N, representing the required length of the PIN.
2. The second line contains the PIN as a string.

outputFormat

Print a single line to standard output (stdout) containing either True if the PIN is valid according to the specifications, or False otherwise.
