In Javascript, Given an array of fast food restaurants, return a new sorted array ranked by the overall satisfaction (highest first). See below for a mathematical representation of the satisfaction formula. If two restaurants have the same satisfaction, the names are compared in ascending lexicographical order (case-insensitive).

In this lab assignment you need to implement the method named middleValue, in a program named ArrayOps.java. The method accepts an array of integer values as a parameter, and returns the value in the middle of the array. For instance, if an array contains five elements, then the third element would be the middle element to be returned. However, if the array contains six elements, both the third and fourth values could be considered to be the middle elements. In this case, only return the first middle value, namely, the third element of the array. Complete the method middleValue, and test the correctness of your method in main(). Particularly, you should create two arrays (arbitrary values), one array with odd length, and the other with even length, and print out the middle values of these two arrays.
Write a program in JAVA to input the number of elements in an array, also input the values in the array from the console. Replace all those elements which are even and greater than 5, with -99. Print the final array. Constraints: The array should initially not contain -99. The value of the number of elements should not be greater than 50.
Write a Java program tat prompts user for a list of integers with 0 as the last value.Save the values in an array. Assume there can be maximum 100 values. Theprogram should have the following methods:- A method that takes the array as parameter and updates each value in thearray to the square of the value.- Another method that takes the original and modified arrays as parametersand displays the original and the squared values.
Write a program named GradeStats.java then implement the following method: public static int[] gradeStats(int[] arr) It accepts int array representing test grades for CISY432 then calculates and returns the following grade statictics: highest, lowest, average, number of grades that are greater than or equal to 70, the number of grades that are less than 70 It returns these five numbers as an int array, and the 1st element is for highest, 2nd for lowest, 3rd for average 4th element for number of grades that are greater than or equal to 70 5th for the number of grades that are less than 70 For example.

Write a Java program (Hangman.java) to play the classic word game Hangman. In the game, a word is randomly selected from an array of possible words. Then, the user is prompted to guess letters in the word one at a time. When the user makes a correct guess, all instances of that letter in the word are shown. When all letters in the word have been guessed, the game ends and the score (number of missed guesses) is displayed. A user can play the game multiple times if they choose. Here is a sample run of a correct program (user input indicated by orange text):Enter a letter in word ******** > cEnter a letter in word c******* > rEnter a letter in word c******r > s s is not in the wordEnter a letter in word c******r > tEnter a letter in word c****t*r > mEnter a letter in word c*m**t*r > t t is already in the wordEnter a letter in word c*m**t*r > pEnter a letter in word c*mp*t*r > oEnter a letter in word comp*t*r > eEnter a letter in word comp*ter >…
Write a method with header static void DisplayIntArray(int[] numbers). The first argument is an array of ints. There is no return value. This method displays all the elements of the argument on a single line. Each item will occupy three columns.Call this method from main with a suitable argument. Write a method with header static int[] GenerateRandomIntArray(int numberOfItems, int largestValue). The first argument is an int indicating the number of elements that will be present in the return array. The second argument is an int representing the largest item in the array. The returned value is an array of integers. This method does the following: Declare and initialized a variable of type Random (Random generator = new Random();) Declare an array of type int (you may call it result) Allocate storage for the correct number of items Using your favorite looping statement, assign a random integer to each element of the array (result[i] = generator.Next(largestValue);) In your…
Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false

Write a complete Java program named Transpose that contains the following: The main method asks the user to provide n - the number of rows and m – the number of columns for a rectangular matrix of integers from 2 to 10. The main method calls the matrixSetUp() method which creates a rectangular matrix of specified dimensions and populates it with random integers from 0 to 99. Hint: You can use Math.random() to generate random numbers. The main method prints the matrix created by the matrixSetUp () method in the form of a matrix. Hint: in order to print the array in the example format, you can use Arrays.toString(matrix[row]) to print each row. The main method calls the matrixTranspose() method that creates and returns a transpose of the initial matrix. Hint: matrix transpose means: ��[��][��]=�[��][��] The main method prints the transpose of the matrix.
This question is in javaYou are walking along a hiking trail. On this hiking trail, there is elevation marker at every kilometer. The elevation information is represented in an array of integers. For example, if the elevation array is [100, 50, 20, 30, 50, 40], that means at kilometer 0, the elevation is 100 meters; at kilometer 1, the elevation is 50 meters; at kilometer 2, the elevation is 20 meters; at kilometer 3, the elevation is 30 meters; at kilometer 4, the elevation is 50 meters; at kilometer 5, the elevation is 40 meters. a) Write a method called dangerousDescent that determines whether there is a downhill section in the hiking trail with a slope of more than -0.05. The slope is calculated by the rise in elevation over the run in distance. For example, the last kilometer section has a gradient of -0.01 because the rise in elevation is 40 - 50 = -10 meters. The distance covered in 1000 meters. -10 / 1000 = 0.01. Your method should return true if there exists a dangerous…

This question is in java The Sorts.java file is the sorting program we looked at . You can use either method listed in the example when coding. You want to add to the grades.java and calculations.java files so you put the list in numerical order. Write methods to find the median and the range. Have a toString method that prints the ordered list, the number of items in the list, the mean, median and range.
