Code a JavaScript function that simulates the Math.pow() method, or the exponent (**) operator, where it accepts two floating point arguments (base and exponent) and returns a valid calculated power value. You are not permitted to use any JavaScript Math object methods or the exponent operator and your function does not need to address negative base or exponent values.

Help me find the problem with this java question

Design and implement an application that reads an integer value representing a year from the user. The purpose of the program is to determine whether the year is a leap year (and therefore has 29 days in February) in the Gregorian calendar. A year is a leap year if it is divisible by 4, unless it is also divisible by 100 but not 400. For example, the year 2003 is not a leap year, but 2004 is. The year 1900 is not a leap year because it is divisible by 100, but the year 2000 is a leap year because even though it is divisible by 100, it is also divisible by 400. Produce an error message for any input value less than 1582 (the year the Gregorian calendar was adopted)

In certain programming languages, comments appear between delimiters such as (# and #).• A comment must begin with (# and end with #).• A comment may not contain #) inside the comment.• A comment’s delimiters must be separate: (##) is a comment, (#) is not.• For simplicity, assume that the alphabet is  = {a, b, (, ), #}.Give a regular expression that accepts comments. ps: I upload the pic of this question

Beta reduce the following lambda expressions, if possible: a) λx.λy.(x y) λy.λx.(x y) b) λx.(x x) λx.(x x)

In C#, Compute the binomial expression (a+b)^2 using the following rubric: Write code for computing the formula (a+b)^2 which expands into the following expression. In your code •Compute squares of double type variables a and b. •Compute the product 2*a*b•Add the squares and the product together •Use Math.POW library to compute the squares of the variables a and b. •Other functional code.

CODE IN C# NOT JAVA (reject if you can't do C# please): Write an application that runs 1,000,000 games of craps and answers the following questions (explain each step): How many games are won on the first roll, second roll, ..., twentieth roll and after the twentieth roll? How many games are lost on the first roll, second roll, ..., twentieth roll and after the twentieth roll? What are the chances of winning at craps? [Note: You should discover that craps is one of the fairest casino games. What do you suppose this means?] What is the average length of a game of craps?

Java Program

In Java, an identifier, which can be class name or method name, is a series (string) of the following groups/types of characters: {fill/continue from 2) (1) Lower-case alphabet characters: a – z, (2) .................... (3) ...................... (4) .................. (5) .............

Ruby Programming: Write a function that takes a number x as a parameter and returns the value of x3 Test the function for values x= 2 and x= 3. Output should be 8 and 27 respectively.

Python Programming: Write a program using unittest.TestCase methods to confirm that the addition and subtraction of date and timedelta objects produce correct results. Important notes: Use the unittest module to create a TestCase to test that the addition and subtraction of date and timedelta objects produce correct results... For example I could create a TestCase with a function that tests the addition of date and timedelta objects; a function that tests the subtraction of date and timedelta and then call unittest's main method at the end. When you run this program, it should tell us whether the text was successful or not. See attached image for what the output should look like.
