Scenario
As you surely know, due to some astronomical reasons, years may be leap or common. The former
are 366 days long, while the latter are 365 days long.
Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the
kind of year:
if the year number isn't divisible by four, it's a common year,
otherwise, if the year number isn't divisible by 100, it's a leap year.
otherwise, if the year number isn't divisible by 400, it's a common year.
otherwise, it's a leap year.
none of the above
year int(input("enter the year"))
if (year%4 1-0) and (year%400 -0) or (year % 1000):
print (year is common year")
else:
print(year, is leap year")
year= int(input ("enter the year"))
if (years !-0) or (year480 1-0) and (year % 1001-0):
print(year is common year")
else:
print(year, "is leap year")
D
year= int(input("enter the year"))

- : Given a boolean expression consisting of the symbols 0 (false), 1 (true), & (AND), I (OR), and / (XOR), and a desired boolean result value result, create a function that counts the number of ways the expression may be parenthesized such that it evaluates to result. The expression should be completely parenthesized (for example, (0) A(1)) but not excessively (for example, (((0)) / (1))).EXAMPLE \scountEval("l/01011", false) yields 2 counts."0&0&0&1All0", true) = 10arrow_forwardThe objective of this program is to demonstrate your proficiency with the if-elif-else construct. Your program will consist of a simple guessing game. Using the random module, generate an integer between 1 and 10. This will be the secret. You will then ask the user for a guess between 1 and 10. . If the guess is greater than the secret respond, "Too high". • If the guess is less than the secret respond, "Too low". . If both numbers are equal respond, "Success!". Remember to test your program to ensure that all of the comparisons work. Please note that a loop is not required. The images below shows the program being run multiple times to display the three different possible output messages. Your display should look like this. User input is highlighted in green.

Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.arrow_forwardThe equation of a line in standard form is ax + by = c , wherein both aand b cannot be zero, and a, b, and c are real numbers. If b≠0, then –a/b is the slope of the line. If a = 0, then it is a horizontal line, and if b = 0, then it is a vertical line. The slope of a vertical line is undefined. Two lines are parallel if they have the same slope or both are vertical lines. Two lines are perpendicular if either one of the lines is horizontal and the other is vertical or the product of their slopes is –1. Design the class lineType to store a line. To store a line, you need to store the values of a (coefficient of x), b (coefficient of y), and c. Your class must contain the following operations: If a line is nonvertical, then determine its slope. Determine if two lines are equal. (Two lines a₁x + b₁y = c₁ and a₂x + b₂y = c₂ are equal if either a₁ = a₂, b₁ = b₂, and c₁ = c₂, or a₁ = ka₂, b₁ = kb₂ and c₁ = kc₂, and for some real number k.) Determine if two lines are parallel.

- Write a program in Java to take an infix mathematical expression. The expression will contain single- or double-digit numbers, ‘+’, ‘-‘, ‘*’, and ‘/’ operators, and parenthesis. First check the validity of the expression with respect to the position of opening and closing parenthesis. If the expression is not valid then display appropriate message, otherwise, convert that infix expression to corresponding postfix expression, evaluate that postfix expression and print the final result. You can use relevant Java built-in classes in your code. The sample inputs/ outputs are given below: Sample inputs and outputs: (User’s inputs are shown in bold) Sample 1 Enter the mathematical expression: 15*(8–3*2)+16/4) The expression is invalid Sample 2 Enter the mathematical expression: 15*(8–3*2)+16/4 The postfix expression: 15 8 3 2 * - * 16 4 / + The final result: 34arrow_forwardWrite a program in Java to take an infix mathematical expression.
