The document discusses implementing a function to check if a character is a hexadecimal digit. It explains that a hexadecimal digit ranges from 0-9, A-F, a-f in the ASCII table. It provides examples of inputting different characters and checking if they are hexadecimal digits or not. The sample execution section is empty. It lists functions as the prerequisite for understanding how to create a custom function to check for hexadecimal digits.
