Problem: A positive (strictly greater than zero) integer is called round if it is of the form d00...0. In other words, a positive integer is round if all its digits except the leftmost (most significant) are equal to zero. In particular, all numbers from 1 to 9 (inclusive) are round.

For example, the following numbers are round: 4000, 1, 9, 800, 90. The following numbers are not round: 110, 707, 222, 1001.

You are given a positive integer n (1 ≤ n ≤ 10^4). Represent the number n as a sum of round numbers using the minimum number of summands (addends). In other words, you need to represent the given number n as a sum of the least number of terms, each of which is a round number.

Input

The first line contains an integer t (1 ≤ t ≤ 10^4) — the number of test cases in the input. Then t test cases follow.

Each test case is a line containing an integer n (1 ≤ n ≤ 10^4).

Output

Print t answers to the test cases. Each answer must begin with an integer k — the minimum number of summands. Next, k terms must follow, each of which is a round number, and their sum is n. The terms can be printed in any order. If there are several answers, print any of them.

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int t;
  cin >> t;
  while (t--) {
    int n;
    cin >> n;
    int d;
    for (int i = 1;; i++) {
      if (n / (int)(pow(10, i) + 0.5) == 0) {
        d = i;
        break;
      }
    }
    vector<int> v;
    d = d - 1;
    while (d >= 0) {
      int a = n / (int)(pow(10, d) + 0.5);
      if (a != 0) {
        a = a * (int)(pow(10, d) + 0.5);
        n = n - a;
        v.push_back(a);
      }
      d--;
    }
    int s = v.size();
    cout << s << endl;
    for (auto itr = v.begin(); itr != v.end(); itr++) {
      cout << *itr << " ";
    }
    cout << endl;
  }
