The problem context involves taking a string input from the user and splitting it into tokens. Tokens are essentially parts of the string that are separated by certain characters. In this case, the characters are commas, spaces, apostrophes, underscores, question marks, and exclamation points.

CodeRankGPT is a tool powered by GPT-4 that quietly assists you during your coding interview, providing the solutions you need.
In real-time and absolutely undetectable 🥷
The solution approach involves first checking if the string contains any alphabetic characters. If it does, the string is split into tokens using the specified characters as delimiters. The number of tokens and the tokens themselves are then printed. If the string does not contain any alphabetic characters, the program simply prints 0.
