1. Reverse a number (integer) by iterative program.Reverse a number:Input: prompt user to enter an integer.Output: print out the integer reversely.e.g.: if user enters 12345, your output will be 54321.2. Reverse a number (integer) by recursive program.3. ADT array-based polynomialsa. Input/outputInput:(1) The degree of the polynomial (the highest degree of all the termsin the polynomial)(2) The coefficient for each term from the highest degree to thelowest degreeOutput:Print out the polynomial.e.g.: if user enters 3 for the degree of the polynomial and enters 7, 0, 9, 10for each term from the highest degree to the lowest degree, then the outputwill be: 7x^3+9x+10b. EvaluationOnce the polynomial has been entered by the user, prompt the user to enterthe value of x and evaluate the polynomial and print out the value of thepolynomial.e.g. if user enter 2 for the value of x (that is, x=1), then you evaluate thepolynomial as 7*2^3+9*2+10=84 and you print out the value of thepolynomial is 84. c. Add two polynomials.Prompt the user to enter two polynomials (as above in step a), then addthese two polynomials and print out the result.e.g.: for the first polynomial, the user enters 3 for the degree of thepolynomial and enters 7, 0, 9, 10 for each term from the highest degree tothe lowest degree; for the second polynomial, the user enters 2 for thedegree of the polynomial and enters 1, 2, 3 for each term from the highestdegree to the lowest degree, then you have:1st polynomial: 7x^3+9x+102nd polynomial: x^2+2x+3After you add these two polynomials: your have 7x^3+x^2+11x+13.

Part 4 Guessing game (random and absolute) Write a program that does this: You (as programmer) are the dealer. Pick a random number for yourself (between 0 and 100). Ask the user to input a random number (between 0 and 100). Whoever is closer to 21 wins the game. If the dealer wins, say "Dealer wins." If the user wins, say “Player wins”. Example output: Player please pick a number. 45 Dealer has 25 Dealer wins. Part 5 Guessing game loop (keeping a counter) Write the same program as in part 4, but keep it going so that it keeps playing (dealing hands and saying who wins) until the User enters the number 21 at which point you print out some stats and say goodbye, for example, your goodbye might look like this: Number of hands played: 5 Dealer won: 3 Player won: 2 You're 2 for 5 Come back to the

Python Programming Only Please: Write a program that asks the user to enter a person’s age. The program should displaya message indicating whether the person is an infant, a child, a teenager, or an adult. Following are the guidelines: • If the person is 1 year old or less, he or she is an infant.• If the person is older than 1 year, but younger than 13 years, he or she is a child.• If the person is at least 13 years old, but less than 20 years old, he or she is a teenager.• If the person is at least 20 years old, he or she is an adult.
A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.
