public class Main {

	public static void main(String[] args) {

		Scanner sc = new Scanner(System.in);

		while(sc.hasNextInt()){
			int n = sc.nextInt();
			int ans = 0;
			while(n-->0){
				ans+=resolve(sc.nextInt());
			}
			System.out.println(ans);
		}

	}

	private static final int[] moneys = new int[]{100, 50, 20, 10, 5, 2};

	private static int resolve(int n){
		int res = 0;
		for(int i=0; i<moneys.length; i++){
			if(n>=moneys[i]){
				res+=n/moneys[i];
				n%=moneys[i];
			}
