	public static void main(String[] args) {
		
		List max = new ArrayList();
		for(int i = 0;i<100;i++){

			 max.add(""+i);
			for(int j =0 ; j <1000; j++){
			
				for(int k = 0 ; k <1000; k++){
					if(5*j+7*k==i){
						max.remove(""+i);
						//System.out.println(i+"\t="+j+"*5+"+k+"*7");
					}
				}
			}
		}
		System.out.println(max);
