ahrayia [7]

Answer:

Here is the JAVA program:

public class Main {  //class name

public static void main(String[] args) {   //start of main method

//sets all boolean type variables spades, hearts diamonds and clubs to false initially

   boolean spades = false;  

   boolean hearts = false;

   boolean diamonds = false;

   boolean clubs = false;  

   String[] deck = new String[4];  //to store card sequence

   int index = 0;  //to store index position

   int NoOfPicks = 0;  //to store number of picks (picks count)

   while (!spades || !hearts || !diamonds || !clubs) {   //loop starts

       String card = printCard(getRandomCard());  //calls printCard method by passing getRandomCard method as argument to it to get the card

       NoOfPicks++;   //adds 1 to pick count

       if (card.contains("Spades") && !spades) {  //if that random card is a card of Spades and spades is not false

           deck[index++] = card;  //add that card to the index position of deck

           spades = true;  //sets spades to true

       } else if (card.contains("Hearts") && !hearts) {  //if that random card is a card of Hearts and hearts is not false

           deck[index++] = card;  

           hearts = true;   //sets hearts to true

       } else if (card.contains("Diamond") && !diamonds) {  //if that random card is a card of Diamond and diamonds is not false

           deck[index++] = card;

           diamonds = true;  //sets diamonds to true

       } else if (card.contains("Clubs") && !clubs) {  if that random card is a card of Clubs and clubs is not false

           deck[index++] = card;

           clubs = true;         }     }   //sets clubs to true

   for (int i = 0; i < deck.length; i++) {  //iterates through the deck i.e. card sequence array

       System.out.println(deck[i]);     }  //prints the card number in deck

   System.out.println("Number of picks: " + NoOfPicks);  }   //prints number of picks

public static int getRandomCard() {  //gets random card

   return (int) (Math.random() * 52); }   //generates random numbers of 52 range

public static String printCard(int cardNo) {   //displays rank number and suit

   String[] suits = { "Spades", "Hearts", "Diamonds", "Clubs", };  //array of suits

   String[] rankCards = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10",

           "Jack", "Queen", "King" };   //array of rank

  int suitNo = cardNo / 13;  //divides card number by 13 and stores to suitNo

 int rankNo = cardNo % 13;   //takes modulo of card number and 13 and store it to rankNo

   return rankCards[rankNo] + " of " + suits[suitNo];  }}  //returns rankCard at rankNo index and suits at suitNo index

Explanation:

The program is explained in the comments attached with each line of code. The screenshot of the program along with its output is attached.

Write a short program using Python that will:
Alexxx [7]

Answer:

// program in Python to check perfect number

#function to find number is perfect or not

def is_Perfect_Number(n):

   #total variable

   tot = 1

   i = 2

   #sum of all divisor of number

   while i*i<=n:

       if n%i==0:

           tot = tot + i + n/i

       if tot == n and n != 1:

           return 1

       i = i+1  

   return 0

#read until user enter a perfect number

while True:

   #read integer

   num = int(input("Input an integer: "))

   #call the function

   if(is_Perfect_Number(num)):

       print(num,"is perfect number")

       #if perfect number break

       break

   else:

       print(num,"is not a perfect number")

       #ask again

   print("try again.")

Explanation:

Read number from user and then call the function is_Perfect_Number() with  parameter "num".This will find the sum of all divisor of number.If sum is  equal to number then it will return 1 else return 0.If the number is not  perfect then it will again ask to enter a number until user enter a perfect  number.

Output:

Input an integer: 24

24 is not a perfect number                                                                                                

try again.                                                                                                                

Input an integer: 28                                                                                                      

28 is perfect number
