Answer: B. Personal Digital Assistant (PDA).
Although some of the other devices listed may have the capability of allowing the use of a digital pen, the use of the pen will be somewhat unnecessary. Let's take the personal computer and laptop for instance. In a personal computer and laptop we already have a mouse or track pad that can be used to navigate and select objects in the computer.
For the smart television, most smart televisions can actually be operated with gestures or voice command, the use of a digital pen will also not help due to the size of the screens of the televisions.
In the past we had some mobile phones that have a stylus as a pointer. This type of technology has now been change to touch screens that are more effective for the different types of mobile being produced now a days.
Most PDA's come with a screen that requires a small amount of pressure to activate commands. Digital pens also come with different functions that allow the device to draw, record audio, and even shortcut commands for these devices. These digital pens input are then converted by device and translated into computer language.

To delete a node from linked list it is best to do it by using two pointers suppose say prev and curr. Iterating over the linked list while curr is not NULL and updating prev also.On finding the node to be deleted we will set the prev so that it points to the next of curr and after removing the link we will free curr from memory.
line of code for deleting a node in c++:-
prev->next=curr->next;
delete curr; or free(curr);

def extract_title(file):
import re
a =''
with open(file,'r') as file:
for line in file:
a += line
m = re.search("^(TITLE)(.*?)(JOURNAL)", a, re.M + re.S)
print(m.groups()[1])
extract_title('new.txt')
Explanation:
The programming language used is python 3.
The function is first defined and the regular expression module is imported.
A variable is initialized to an empty string that will hold the content of the GenBank formatted file.
The file is opened and every line in the file is assigned to the string variable. The WITH statement allows files to be closed automatically.
Regular expression is used to capture all the files between TITLE and JOURNAL in a group.
The group is printed and the function is called.
I have attached a picture of the code in action.
