The Message in the Noise

The radio transmission is drowning in garbage — but the real words contain only letters. Filter, then read. 📻

You get the received tokens. A real word has no digits in it. Print the real words joined by spaces, or no message.

Example:

Input: tokens = ["meet", "x9z", "me", "42b", "at", "noon7", "dawn"] Output: meet me at dawn

Filtering out any token with a digit removes "x9z", "42b", and "noon7", leaving the real words meet, me, at, dawn.
