Select all snippets of code that print the following sequence of `n` lines, where `n` is a positive integer that is already defined. The th line in the output corresponds to the first Fibonacci numbers, for . Assume that and are the first two Fibonacci numbers. There should be a single space after every number, including after the last number in any given line.
Sample output for `n = 7`:
```
