problem
Taro often shop at JOI general stores. At JOI general stores, there are enough coins of 500 yen, 100 yen, 50 yen, 10 yen, 5 yen, and 1 yen, and we always pay the change so that the number of coins is the smallest. Create a program to find the number of coins included in the change you receive when Taro goes shopping at the JOI general store and puts out one 1000 yen bill at the cash register.
For example, in the case of input example 1, 4 must be output as shown in the figure below.

input
The input consists of multiple datasets. Each dataset consists of one line, and only one amount (an integer of 1 or more and less than 1000) paid by Taro is written. The input data ends with one zero line.
The number of datasets does not exceed 5.
output
Output the number of coins included in the change for each dataset on one line.

problem
Taro often shop at JOI general stores. At JOI general stores, there are enough coins of 500 yen, 100 yen, 50 yen, 10 yen, 5 yen, and 1 yen, and we always pay the change so that the number of coins is the smallest. Create a program to find the number of coins included in the change you receive when Taro goes shopping at the JOI general store and puts out one 1000 yen bill at the cash register.
For example, in the case of input example 1, 4 must be output as shown in the figure below.
<image>
input
The input consists of multiple datasets. Each dataset consists of one line, and only one amount (an integer of 1 or more and less than 1000) paid by Taro is written. The input data ends with one zero line.
The number of datasets does not exceed 5.
output
Output the number of coins included in the change for each dataset on one line.

Kuroni isn't good at economics. So he decided to found a new financial pyramid called Antihype. It has the following rules:
1. You can join the pyramid for free and get 0 coins.
2. If you are already a member of Antihype, you can invite your friend who is currently not a member of Antihype, and get a number of coins equal to your age (for each friend you invite).
n people have heard about Antihype recently, the i-th person's age is a_i. Some of them are friends, but friendship is a weird thing now: the i-th person is a friend of the j-th person if and only if a_i AND a_j = 0, where AND denotes the [bitwise AND operation](https://en.wikipedia.org/wiki/Bitwise_operation#AND).
Nobody among the n people is a member of Antihype at the moment. They want to cooperate to join and invite each other to Antihype in a way that maximizes their combined gainings. Could you help them?
Input
The first line contains a single integer n (1≤ n ≤ 2⋅ 10^5) — the number of people.
The second line contains n integers a_1, a_2, ..., a_n (0≤ a_i ≤ 2⋅ 10^5) — the ages of the people.
Output
Output exactly one integer — the maximum possible combined gainings of all n people.

Only the first and second persons are friends. The second can join Antihype and invite the first one, getting 2 for it.

Vanya has a scales for weighing loads and weights of masses w0, w1, w2, ..., w100 grams where w is some integer not less than 2 (exactly one weight of each nominal value). Vanya wonders whether he can weight an item with mass m using the given weights, if the weights can be put on both pans of the scales. Formally speaking, your task is to determine whether it is possible to place an item of mass m and some weights on the left pan of the scales, and some weights on the right pan of the scales so that the pans of the scales were in balance.
Input
The first line contains two integers w, m (2 ≤ w ≤ 109, 1 ≤ m ≤ 109) — the number defining the masses of the weights and the mass of the item.
Output
Print word 'YES' if the item can be weighted and 'NO' if it cannot.

Provide tags and a correct Python 3 solution for this coding contest problem.
Vanya has a scales for weighing loads and weights of masses w0, w1, w2, ..., w100 grams where w is some integer not less than 2 (exactly one weight of each nominal value). Vanya wonders whether he can weight an item with mass m using the given weights, if the weights can be put on both pans of the scales. Formally speaking, your task is to determine whether it is possible to place an item of mass m and some weights on the left pan of the scales, and some weights on the right pan of the scales so that the pans of the scales were in balance.
Input
The first line contains two integers w, m (2 ≤ w ≤ 109, 1 ≤ m ≤ 109) — the number defining the masses of the weights and the mass of the item.
Output
Print word 'YES' if the item can be weighted and 'NO' if it cannot.
Examples
Input
3 7
Output
YES
Input
100 99
Output
YES
Input
100 50
Output
NO
Note
Note to the first sample test. One pan can have an item of mass 7 and a weight of mass 3, and the second pan can have two weights of masses 9 and 1, correspondingly. Then 7 + 3 = 9 + 1.
Note to the second sample test. One pan of the scales can have an item of mass 99 and the weight of mass 1, and the second pan can have the weight of mass 100.
Note to the third sample test. It is impossible to measure the weight of the item in the manner described in the input. | instruction | 0 | 12,882 | 10 | 25,764 |

Correct Solution:
```
#!/usr/bin/env python3
import sys
w, m = list(map(int, sys.stdin.readline().split()))
a = sum(pow(w, i) for i in range(101)) + m
while a > 0:
if a % w > 2:
print('NO')
sys.exit(0)
a //= w
print('YES')
