(Converting a given date to the day number in the year)
Write a program that prints the day number of the year, given the date is in the
form month day year. For example, if the input is 1 1 05, the day number is 1; if the
input is 12 25 05, the day number is 359. The program should check for a leap year. A
year is a leap year if it is divisible by 4 but not divisible by 100. For example, 1992 and
2008 are divisible by 4, but not by 100. A year that is divisible by 100 is a leap year if it
is also divisible by 400. For example, 1600 and 2000 are divisible by 400. However,
1800 is not a leap year because 1800 is not divisible by 400.
Directions:
Call 3 functions from your main.
One to input data (pass parameters in a list)
One to determine the result (use a value returning function to determine and
return the result)
One to display both the date and the result
You can use two Python dictionaries to represent the number of days in each
month for a regular and a leap year.

(Count positive and negative numbers and compute the average of numbers)
Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number.
*********** USE PYTHON *********
Sample Run 1
Sample Output 1:
Enter an integer, the input ends if it is 0: 1
Enter an integer, the input ends if it is 0: 2
Enter an integer, the input ends if it is 0: -1
Enter an integer, the input ends if it is 0: 3
Enter an integer, the input ends if it is 0: 0
The number of positives is 3
The number of negatives is 1
The total is 5
The average is 1.25
Sample Run 2
Sample Output 2:
Enter an integer, the input ends if it is 0: 0
No numbers are entered except 0
(Find future dates) Write a program that prompts the user to enter an
integer for today’s day of the week (Sunday is 0, Monday is 1, …, and Saturday is
6). Also prompt the user to enter the number of days after today for a future day
and display the future day of the week.

- Please take screenshots of the stops. (Science: calculating energy) Write a program that calculates the energy needed to heat water from an initial temperature to a final temperature. Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperatures of the water. The formula to compute the energy is Q = M * (finalTemperature – initialTemperature) * 4184 where M is the weight of water in kilograms, temperatures are in degrees Celsius, and energy Q is measured in joules.arrow_forward(In python please) Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs Yes if every character is a digit 0-9 or No otherwise. Ex: If the input is: 1995 the output is: Yes Ex: If the input is: 42,000 or any string with a non-integer character, the output is: Noarrow_forward(Phone key pads) The international standard letter/number mapping found on the telephone is shown below: 100 2 abc 3 def 4 ghi 5 ikl 6mno 7pgrs 8 tuv 9wxyz Write a program that prompts the user to enter a letter and displays its correspond- ing number.arrow_forward
- (Find the two highest scores)Write a program that prompts the user to enter the number of students and each student’s name and score, and displays the name and score of the student with the highest score and the student with the second-highest score.Sample RunEnter the number of students: 5Enter a student name: SmithEnter a student score: 60Enter a student name: JonesEnter a student score: 96Enter a student name: PetersonEnter a student score: 85Enter a student name: GreenlawEnter a student score: 98Enter a student name: ZhangEnter a student score: 95Top two students:Greenlaw's score is 98.0Jones's score is 96.0arrow_forwardFind the error(s) in the following code: (6)arrow_forward(Geometry: distance of two points) Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is: Square root of ((x2 - x1) squared + (y2 - y1) squared) Note that you can use pow(a, 0.5) to compute square root of a. Sample Run Enter x1 and y1: 1.5 -3.4 Enter x2 and y2: 4 5 The distance between the two points is 8.764131445842194arrow_forward

- (PYTHON) A Krishnamurthy number is a number which sum of the factorial of its digits is equal to the number itself. For example: Let us consider the number 145. Factorial sum = 1! + 4! + 5! = 1 + 24 + 120 = 145. Therefore 145 is a Krishnamurthy number. Other examples include: 1, 2, 40585. Write a program that does the following: • asks the user to input an integer. • computes whether the number is a Krishnamurthy number. • then finally prints the result. Note: You are not allowed to use the built-in function math.factorial.arrow_forward5. (Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the following 2 X 2 system of linear equation: ax + by = e cx + dy = f ● x = ed - bf bc ad y = af - ec ad bc - Write a program that prompts the user to enter a, b, c, d, e, and f and display the result. If ad- bc is 0, report that The equation has no solution. Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter x is -2.0 and y is 3.0 Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter The equation has no solutionarrow_forward(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. Here is the sample output: You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of value Step 2: Repeat Step 1 until we get a single digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise notarrow_forward
