Problem Statement

Use the `enum` module to create a `Status` Enum with `PENDING = 1`, `ACTIVE = 2`, and `CLOSED = 3`. Read an integer, instantiate the Enum by value, and print ‘Status: [name]’. Catch a `ValueError` if invalid and print ‘Invalid’.

Input Format

A single integer.

Output Format

Print the enum name or 'Invalid'.

Constraints

None

Sample Input

Sample Output

Status: ACTIVE

Explanation

Enums bundle closely related constant states into a readable and strictly validated structure.

Starter Code

from enum import Enum

# Define the Status Enum here

if __name__ == '__main__':
    val = int(input().strip())
    # Evaluate safely and print
    pass
