Answer:

In Java:

import java.util.*;

public class Main{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int n;

System.out.print("Max of series: ");

n = input.nextInt();

for(int i = 1; i<=n;i+=4){

System.out.print(i+" ");

}

Explanation:

This declares n as integer. n represents the maximum of the series

int n;

This prompts the user for maximum of the series

System.out.print("Max of series: ");

This gets user input for n

n = input.nextInt();

The following iteration prints from 1 to n, with an increment of 4

for(int i = 1; i<=n;i+=4){

System.out.print(i+" ");

}

Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of o

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

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

True / False General purpose registers can be read and written by ML programs

Oduvanchick [21]

Answer: False

Explanation:

General purpose register cannot be read and written by the Ml program because when ever the instruction decode the input and output unit are invoke for data to read in the memory and it can written to the output device from the memory. General purpose register stored both the addresses and the data in the file. In some cases ML only reads with the hep of special algorithm function.
