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.
