## Entropy with Shannon

What is the Shannon Entropy of "Web3Mantra" after turning it into Base64, then to consecutive Hex (no space or any delimiters)? To generate the flag, insert the value with exactly 17 digits after the decimal point, for example: PC{4.325817531314781}

Steps: Base64 -> Hex (None delimiters) -> Shannon entropy up to 17 digits

If you have solved this challenge, please send your code along with the registration.
