When analyzing data, such as the output of the rolling average method from the previous problem, it is sometimes useful to identify where the (local) maximum valucs arc located. We'll call these max- imal values peaks in the data. More formally, if we have a sequence of numbers do, d1, d2, ..., dn-1, the peaks are identified as follows:

QUICKLY please. Thank you. Please answer in python quickly Below is code that defines a Quadrilateral class (a shape with four sides), which has four floating point instance variables that correspond to the four side lengths: import math class Quadrilateral: def __init__(self,a,b,c,d): self.a = a self.b = b self.c = c self.d = d def perimeter(self): return self.a + self.b + self.c + self.d def area(self): print("Not enough information") def __lt__(self, other): return self.perimeter() < other.perimeter() Define a Rectangle class that inherits from Quadrilateral, with the following methods: __init__(self, length, width): Override the __init__ method so that the Rectangle constructor only takes in two floating point numbers. Your constructor for Rectangle should only consist of a call to Quadrilateral’s constructor: don’t define any new instance variables. Override the area method to...

PROBLEM STATEMENT: Return the longest String! public class LongestString{public static String solution(String firstWord, String secondWord){// ↓↓↓↓ your code goes here ↓↓↓↓return null;}} Can you help me with this Java Question

Q: What's a better way to write this? (C#) public string SomeMethod(string OriginalZip) { string zip = "Zip Not Available"; zip = GetZip(zip, OriginalZip); return zip; } private static string GetZip(string zip, string OriginalZip) { int zipLength = (OriginalZip.HasValue) ? OriginalZip.Value.ToString().Length: 0; int NumOf Leading Zeroes = (zipLength> O && zipLength < 5) ? 5 - zipLength: 0; if (OriginalZip.HasValue) { i++) } zip = OriginalZip.Value.ToString(); for (int i = 0; i < NumOf Leading Zeroes; { } zip = "0" + zip; } return zip;

Java true or false: The method public boolean simpleMethod() { return true; } is a valid mutator?

Random Numbers: Most computer programs do the same thing every time they run; programs like that are called deterministic. Usually, determinism is a good thing, since we expect the same calculation to yield the same result. But for some applications, we want the computer to be unpredictable. Games are an obvious example, but there are many others, like scientific simulations. We have already seen java.util.Random, which generates pseudorandom numbers. The method nextInt takes an integer argument, n, and returns a random integer between 0 and n - 1. Assignment: For this assignment you will write a program in java to simulate a guessing game. Your program will generate a random number in a certain range (let the user define the range) and ask the user to guess what number it is. Give the user a certain number of tries while you narrow down the possibilities. For example, let's say the number generated is 67 and the user has 5 tries, this could be your program's output: This is a guessing...

Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of 35ドル.00. The first five letters or numbers are included in the minimum charge; there is a 4ドル charge for each additional character. If the sign is made of oak, add 20ドル.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional 15ドル charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the...
