Number and Digits Problem Statement

You are provided with a positive integer N. Your task is to identify all numbers such that the sum of the number and its digits equals N.

Example:

Input:
N = 21
Output:
[15]
Explanation:

The only number where the sum of the number and its digits equals 21 is 15, as 15 + 1 + 5 = 21.

Constraints:

  • 1 <= T <= 10
  • 1 <= N <= 10^{12}
  • Time Limit: 1 sec

Input:

The first line contains a single integer ‘T’ representing the number of test cases.
Each test case consists of a single integer ‘N’, which represents the given integer.

Output:

For each test case, print all space-separated integers whose sum of digits with themselves is equal to ‘N’ in increasing order. Print -1 if no such integer exists.
Print a separate line for each test case.
Note:
You do not need to print anything, it has already been taken care of. Just implement the given function.
