Valid Username Checker

You are given a username string. Your task is to validate the username based on the following criteria:

• The length of the username must satisfy \(5 \leq |username| \leq 15\).
• The username can contain only lowercase English letters (a to z).
• The username must contain at least one vowel (a, e, i, o, or u).

If the username meets all the criteria, output Valid; otherwise, output Invalid.

Note: All formulas are in LaTeX format. For example, the length constraint is given by \(5 \leq |username| \leq 15\).
