📖 Description

The check_valid_chars function iterates through each element of the 2D map array and compares it against a predefined set of valid characters (VALID_CHARS).

• The function first checks if the map or the map array is NULL, returning false if so.
• It loops through each row and each character in the map.
• For each character, it checks whether it exists in the VALID_CHARS array.
• If any character is not in the valid set, the function immediately returns false.
• If all characters are valid, the function returns true.

💡 Example Usage

if (check_valid_chars(&map)) {
    printf("All characters in the map are valid.\n");
} else {
    printf("Map contains invalid characters.\n");
}
