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:
t = int(input())
a = []
for i in range(t):
    i = int(input())
    a.append(i)
for i in a:
    k = 0
    b = []
    n1 = (i//1000)*1000
    if n1 != 0: k += 1
    n2 = ((i%1000)//100)*100
    if n2 != 0: k += 1
    n3 = (((i%1000)%100)//10)*10
    if n3 != 0: k += 1
    n4 = ((i%1000)%100)%10
    if n4 != 0: k += 1
    print(k)
    c = [n1, n2, n3, n4]
    for i in c:
        if i != 0:
            b.append(i)
    print(' '.join(map(str, b)))
