Solution:
It is important because, it has to do operation on so without, data structures and algorithms.
It performs these operation:
1)Take an input
2) Process it
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps.
Answer:
A primary key is a special relational database table column (or combination of columns) designated to uniquely identify each table record. A primary key is used as a unique identifier to quickly parse data within the table. A table cannot have more than one primary key.

Explanation:
The following code is written in Python it doesn't use any loops, instead it uses a recursive function in order to continue asking the user for the inputs and count the number of positive values. If anything other than a number is passed it automatically ends the program.
def countPos(number=input("Enter number: "), counter=0):
try:
number = int(number)
if number > 0:
counter += 1
newNumber = input("Enter number: ")
return countPos(newNumber, counter)
else:
newNumber = input("Enter number: ")
return countPos(newNumber, counter)
except:
print(counter)
print("Program Finished")
countPos()
Answer:
True is the correct answer for the above question.
Explanation:
- An online survey is done with the help of social sites that connects many people in conversation from all over the world. So to do an effective survey, it is best to choose the online medium.
