return "File not found"
#taking the file name from user
filename = input("Enter a file name: ")

print("\ndoc_sting: \n"+ readFileFirstLast.__doc__+"\n")
#printing the returned string by calling the readFileFirstLast()
print("output string :")
print(readFileFirstLast(filename))

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.
