Chapter 22, Problem 22.25PE

(Game: Sudoku) Revise Programming Exercise 22.21 to display all solutions for the Sudoku game, as shown in Figure 22.17a. When you click the Solve button, the program stores all solutions in an ArrayList. Each element in the list is a two-dimensional 9-by-9 grid. If the program has multiple solutions, the Next button appears as shown in Figure 22.17b. You can click the Next button to display the next solution and also add a label to show the solution count. When the Clear button is clicked, the cells are cleared and the Next button is hidden as shown in Figure 22.17c.

FIGURE 22.17 The program can display multiple Sudoku solutions. Source: Copyright © 1995–2016 Oracle and/or its affiliates. All rights reserved. Used with permission.

def winning_card(cards, trump=None): Playing cards are again represented as tuples of (rank,suit) as in the cardproblems.pylecture example program. In trick taking games such as whist or bridge, four players each play one card from their hand to the trick, committing to their play in clockwise order starting from the player who plays first into the trick. The winner of the trick is determined by the following rules:1. If one or more cards of the trump suit have been played to the trick, the trick is won by the highest ranking trump card, regardless of the other cards played.2. If no trump cards have been played to the trick, the trick is won by the highest card of the suit of the first card played to the trick. Cards of any other suits, regardless of their rank, are powerless to win that trick.3. Ace is the highest card in each suit.Note that the order in which the cards are played to the trick greatly affects the outcome of that trick, since the first card played in the trick…

Individual Exercise: Sieve of Eratosthenes O The Sieve of Eratosthenes is a technique for finding all the prime numbers up to a given last number. o It can be implemented as a program by using the algorithm (steps) given below. " Create a variable for the last number initialized as 100 etc. (e.g., int lastNumber = 100;) • Create a boolean array isPrime[] to keep track of which numbers up to lastNumber are prime. O The length of the array must be equal to lastNumber + 1 as the array indexes start from zero. o Note: The default value is false for all the array elements when a boolean array is created by using new. ' Set all the array elements beginning from index = 2 (the first prime number) to true. ' Outer loop: Repeat the following steps for each number num within 2 <= num <= lastNumber / num. o if isPrime[num] is true (meaning that num is prime as no factors exist for num): " Inner loop: Set the isPrime[] elements for all the multiples of num to false. O When the nested loop ends,…
