A. The Fibonacci numbers are the numbers in the following integer sequence.
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ……..
B. Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example, factorial of 6 is 6*5*4*3*2*1 which is 720.
n! = n * (n - 1) * …….. 1
Define what an algorithm is and outline the characteristics of a good algorithm. Write the algorithms to display the Fibonacci series and the factorial value for a given number using Pseudo code. Determine the steps involved in the process of writing and executing a program.
Take a sample number and dry run the above two algorithms. Show the outputs at the end of each iteration and the final output. Examine what Big-O notation is and explain its role in evaluating efficiencies of algorithms. Write the Python program code for the above two algorithms and critically evaluate their efficiencies using Big-O notation.

You are a Windows developer for a data analysis company. For one of your applications you need to create a keyword searching form that asks for a filename and a keyword from the user (as shown in below figure). The form should search for the keyword in the file and display the number of lines that contain the keyword in the results group box. Your form assumes that the entered keyword is a single word. If it is not a single word, you need to create and throw an exception for that case.
Write a C program that takes in the radius (as in integer) of a circle from user and calculate and display the area of the circle
a = input("Enter an animal: ")
s = input("Enter a sound: ")
e = "E"
print("Old Macdonald had a farm "+ e)
print("And on his farm he had a" + a + "," + e)
print("With a " + a + "-" + a + " here and a " + s + "-" + s + " there")
print("Here a "+ s+ " there a " +s)
print("Everywhere a" + s + "-" + a )
print("Old Macdonald had a farm, " + e)
Can you please figure this out.

Exercise 3 : Practice to manipulate 2D arrays
Use a double-subscripted array to solve the following problem. A company has four salespeople ( 1 to 4) who sell five different products ( 1 to 5). Once a day, each salesperson passes in a slip for each different type of product sold. Each slip contains:
a) The salesperson number
b) The product number
c) The total dollar value of that product sold that day
Assume that the information from all the slips for a day is available. Write a program that will read all this information for the day and store in a double-subscripted array sales. For each product find and display the total sales.
each for implementation.
