Question

Write a filter that reads in a sequence of integers and prints the integers, removing repeated values that appear consecutively. For example, if the input is 1 2 2 1 5 1 1 7 7 7 7 1 1 1 1 1 1 1 1 1, your program should print 1 2 1 5 1 7 1.

Answer 1

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.
