Explanation:
In general, when a program runs in text-based environment like command line interface, the program is used for determining the order in which things happen.
As the program runs, the user will not have any choice and he or she can enter the required data.
If the user enters the data in required format then, he/she can get the result or output in desired format.
Answer:
(Assuming Java)
public ArrayList diff(ArrayList list1, ArrayList list2) {
ArrayList<Integer> union = new ArrayList<>();
for (int element : list1) {
union.add(element);
}
for (int element : list2){
if (!union.contains(element)) {
union.add(element);
}
}
return union;
}
Explanation:
Create an ArrayList that has the union of list1 and list2.
First for loop copies all elements into the union array list.
Second for loop adds all elements that are not yet in the union arraylist to the union arraylist.
(Keep in mind that I assume that you mean a mathematical union, so no duplicates. If this is not what you mean, remove the if statement in the second for loop)
Answer:
Following is the code for filter:
public class filter
{ public static void main(String[] args)
{ int x = StdIn.readInt();
System.out.print(" " + x + " ");
while(!StdIn.isEmpty())
{ int y = StdIn.readInt();
if(y != x)
System.out.print(" " + y + " ");
x = y;
}
}
}
Explanation:
- A public class filter is used.
- The main function will accept a single argument as string[], it is also known as java command line argument.
- Now the Stdln.readInt is used to read the integers in the sequence and store it in integer x.
- The value stored in variable x will be printed using System.out.print
- Now unless the Stdln.readInt gets an empty value, check each value of sequence and store in variable y.
- If y is not equal to previous value x, print it and shift the value of y into x.
- Repeat the loop again.

Answer:
First for loop is for printing the rows.
Then we set currColumnLetter to 'A' for first time
Second for loop is for printing the columnletter with each row
