B. Quasi Binary：题目

这题目建议挪到1000分，它不配1400

#include <bits/stdc++.h>
using namespace std;
#define int long long
vector<int> a((int)6e5);
vector<int> b((int)6e5), c((int)6e5);
const int mod = 1e9 + 7;
signed main()
{string str;cin >> str;int n = str.length();int res = 0;for (int i = 0; i < n; i++){int u = str[i] - '0';res = max(res, u);}cout << res << endl;for (int j = 0; j < res; j++){int cou = 0;for (int i = 0; i < n; i++){cou *= 10;int u = str[i] - '0';if (u){cou++;str[i]--;}}cout << cou << " ";}
}
