Problem 5: (Practice Problem: Due Tuesday 4/21/2020)Write a method, getFoodCost which takes three arguments: the first oneis a string named fooditem, the second one is an array of string calleditems, and a third one is an array of double called price. So, when theuser gives a food item name it finds the item in the items array and getsthe corresponding price from the price array. It returns the price whichis a double to the caller.

Write some code that will call a method that takes an integer array as an argument (and initialises the array in the main function), and that method will return the number that is lowest in the list. Below is a portion of the programme. public class Min has the following methods and properties: public static void main(String[, args]), int arr = System.out.print(minimum(arr);
Problem 11 of an Create a class ArraysAndMethodsGames, Write a method that returns the average array with the following header: public static double average(double[] array); Write a method to initialize the array with the following header: public static double[] readArray(): The readArray method prompts the user to enter ten double values and initializes a newly array with these values. It returns the array to main. The method main calls the method Method main prints the array as well. created average and prints the average. 8 Of 9 – SLCC, ASDV 1220, Lab17 Problem 12 Modify class ArraysAndMethodsGames by adding a method that finds the smallest element in an array of double values using the following header: public static double min(double[] array); Call it from main to test it with an array you create in main.
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

PYTHON: This exercise is a variation on "instrumenting" the recursive Fibonacci program to better understand its behavior. Write a supporting method that counts how many times the fib function is called to compute fib (n) where n is a user input. Hint: To solve this problem, you need an accumulator variable whose value "persists" between calls to fib. You can do this by making the count an instance variable of an object. Create a FibCounter class with the following methods: _init_(self) Creates a new FibCounter, setting its count instance variable to 0. getCount(self) Returns the value of count. fib(self, n) Recursive function to compute the nth Fibonacci number. It increments the count each time it is called. resetCount(self) Sets the count back to 0.
