Given a number N. Print the digits of that number from right to left separated by space.

Input
First line contains a number T (1 ≤ T ≤ 10) number of test cases.

Next T lines will contain a number N (0 ≤ N ≤ 109)

Output
For each test case print a single line contains the digits of the number separated by space.

Example
