Each character in hand can only be used once.If we are trying to spell a word with two A's in it, there must be at least two A's in hand. hand the jumble of characters available to spell with word the word that we are testing trying to spell return true if the characters in hand can be used to spell the word; otherwise, false. public static boolean canSpell( char[] hand, char[] word ) { Type the code; } Tests Cases /// Validates that the canSpell correctly indicates a hand that /// does not contain the correct letters cannot spell the word public static boolean unitTest2_1() { String hand = "ZAMIT"; String word = "AMAZE"; boolean result = TileGame.canSpell(hand.toCharArray(), word.toCharArray() ); if(result) { return false; } return true; } /// Validates that canSpell correctly indicates a hand that contains /// all matching letters but too few of the letters cannot spell the /// word public static boolean…arrow_forwardWrite code to complete DoublePennies()'s base case. Sample output for below program:Number of pennies after 10 days: 1024 Note: These activities may test code with different test values. This activity will perform three tests, with startingPennies = 1 and userDays = 10, then with startingPennies = 1 and userDays = 40, then with startingPennies = 1 and userDays = 1. #include <iostream>using namespace std; // Returns number of pennies if pennies are doubled numDays timeslong long DoublePennies(long long numPennies, int numDays){long long totalPennies; /* Your solution goes here */ else {totalPennies = DoublePennies((numPennies * 2), numDays - 1);} return totalPennies;} // Program computes pennies if you have 1 penny today,// 2 pennies after one day, 4 after two days, and so onint main() {long long startingPennies;int userDays; startingPennies = 1;userDays = 10;cout << "Number of pennies after " << userDays << " days: "<< DoublePennies(startingPennies,…arrow_forward

Create a new Java application called "WeightedAvgDropSmallest" (without the quotation marks) according to the following guidelines. The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the weighted average of all those numbers except the lowest n numbers, where n and the weight are also given by the user, and displays all the numbers, the weight, the number of lowest numbers dropped, and the calculated average to the user. The program uses methods to: Get the numbers used to calculate the average. Get the number of lowest numbers to drop before calculating the average. Get the weight, a double greater than 0 and less than or equal to 1. Calculate the weighted average of the numbers (except the lowest n numbers) entered by the user. Print the results. 1. The first method should take no arguments and return an array list of doubles. 2. The second method…arrow_forwardvar x = “blue”; is there anything that you would change if you see the above variable declaration?[arrow_forward
