DIY: UTF-8 Validation
Explore how to validate UTF-8 encoding through Java programming by implementing checks for 1 to 4 byte characters. Understand the rules for UTF-8 byte sequences, enabling you to verify encoding validity and apply this knowledge to cyber security tasks such as packet validation and message integrity.

Problem description
Given an integer array data, return whether it is a valid UTF-8 encoding.
A character in UTF8 can be from 1 to 4 bytes long, subject to the following rules:
- For a
1byte character, the first bit of the packet is0, followed by its Unicode code. - For an
n-bytescharacter, the first
