B'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. 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 ). 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. '...
