Given two polynomials A and B, write a program that adds the given two polynomials A and B.
The first line contains a single integer M.
Next M lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes co-efficient of Pi for polynomial A.
After that next line contains a single integer N.
Next N lines contain two integers Pj, Cj separated with space, where Pj denotes power and Cj denotes co-efficient of Pj for polynomial B.
If M = 4 and for polynomial A
For power 0, co-efficient is 5
For power 1, co-efficient is 0
For power 2, co-efficient is 10
For power 3, co-efficient is 6.
Then polynomial A represents "6x^3 + 10x^2 + 5", the polynomial B represents "4x^2 + 2x + 1" and the addition of A and B is "6x^3 + 14x^2 + 2x + 6"

Secret Message - 2
Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.
Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.

Input
The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).
Output
The output should be a single line containing the secret message. All characters in the output should be in lower case.
Explanation
For example, if the given input is "python", "p" should replaced with "16", similarly"y" with "25","t" with "20","h" with "8","o" with "15","n" with "14". So the output should be "16-25-20-8-15-14".secret Message
Given a string, write a program to mirror the characters of the string in alphabetical order to create a secret message.
Note: Mirroring the characters in alphabetical order replacing the letters 'a' with 'z', 'b' with 'y', ... , 'z' with 'a'. You need to mirror both uppercase and lowercase characters. You can ignore mirroring for all characters that are not letters.

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).Output
The output should be a single line containing the secret message. All characters in the output should be in lower case.
Explanation
For example, if the given input is "python", "p" should replaced with "k", similarly "y" with "b", "t" with "g", "h" with "s", "o" with "l", "n" with "m". So the output should be "kbgslm".

Non-Adjacent Combinations of Two Words
Given a sentence as input, find all the unique combinations of two words and print the word combinations that are not adjacent in the original sentence in lexicographical order.
Input
The input will be a single line containing a sentence.
Output
The output should be multiple lines, each line containing a valid unique combination of two words. The words in each line should be lexicographical order and the lines as well should be in lexicographical order. A valid combination will not contain the words that appear adjacent in the given sentence. Print "No Combinations" if there are no valid combinations.

3.Write an Employee class that keeps data attributes for the following pieces of information:
a. Employee name
b. Employee number Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information:
c. Shift number (an integer, such as1 for morning shift, 2 for evening shift)
d. Hourly pay rate Write the appropriate accessor and mutator methods for each class.
2. Write a class named Pet, which should have the following data attributes:
a) __name (for the name of a pet) __animal_type (for the type of animal that a pet is. Example values are ‘Dog’, ‘Cat’, and ‘Bird’) __age (for the pet’s age)
The Pet class should have an __init__ method that creates these attributes. It should also have the following methods:
b) set_name: This method assigns a value to the __name field. set_animal_type: This method assigns a value to the __animal_type field. set_age: This method assigns a value to the __age field. get_name: This method returns the value of the __name field. get_animal_type: This method returns the value of the __animal_type field. get_age: This method returns the value of the __age field.
1.Write a class named Car that has the following data attributes:
a) __year_model (for the car’s year model) __make (for the make of the car) __speed (for the car’s current speed)
The Car class should have an __init__ method that accepts the car’s year model and make as arguments. These values should be assigned to the object’s __year_model and __make data attributes. It should also assign 0 to the __speed data attribute.
The class should also have the following methods:
b)Accelerate: The accelerate method should add 5 to the speed data attribute each time it is called. Brake: The brake method should subtract 5 from the speed data attribute each time it is called. get_speed: The get_speed method should return the current speed
1. Design a recursive function that accepts an integer argument, n, and prints every second number from n down to a minimum of 0. Assume that n is always a positive integer.
