Answer 1

Here the solution for above problem in java. I have used print method in java to print output in same line, also for to avoid comma in last element i ran the loop till second last element

CODE IN JAVA

import java.util.*;
import java.io.*;
public class Main
{
   public static void main(String[] args) {
//SCANNING FOR INPUT  
       Scanner sc = new Scanner(System.in);
String line = sc.next();
//SPLITING THE STRING BASED ON COMMAN
String[] vector = line.split(",");
int x;
int i;
//ITERATING THROUGH ALL NUMBER PRESENT
for(i=0;i<vector.length-1;++i)
{
//PARSING THE INTEGER X
x=Integer.parseInt(vector[i]);
//PRINTING THE VALUE ON CONSOLE PRINT METHOD IS USED AS IT DOES NOT LEAVE NEW LINE
System.out.print(x);
System.out.print(",");
System.out.print(x);
System.out.print(",");
}
//FOR LAST ELEMENT IGNORING THE LAST COMMA
x=Integer.parseInt(vector[i]);
System.out.print(x);
System.out.print(",");
System.out.print(x);
System.out.println("");
  
   }
}
