        Scanner sc = new Scanner(System.in);
        
        System.out.print("Enter a string: ");
        String str = sc.nextLine();     //Taking String Input
        
        
        byte[] ch = str.getBytes();     //Storing Bytes of String in an array
        
        String newstr = "";         //newstr will contain the newer modified string
        
        newstr = newstr + (char)ch[0];
        for(int i=1;i<ch.length;i++)
        {
            if(ch[i]!=ch[i-1])      //A character from str is added to newstr only if it is not a consecutive one.
            {            
                newstr = newstr + (char)ch[i];
            }
        }
