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 PYTHON3):

Solution:
number_list = lambda: list(map(int, input().split()))
arr2d = lambda rows, cols, v=0: [[v for i in range(cols)] for _ in range(rows)]
t = int(input())
while t > 0:
    n = int(input())
    res = []
    i = 0
    while n > 0:
        d =  n % 10
        n = int(n / 10)
        if d == 0:
            i+=1
            continue
        res.append(d * (10 ** i))
        i += 1
        
    print(len(res))
    for v in res:
        print(v)
