Print the pattern by using one loop | Set 2 (Using Continue Statement)

Given a number n, print triangular pattern. We are allowed to use only one loop.
Example:

```Input: 7
Output:
*
* *
* * *
* * * *
* * * * *
* * * * * *
* * * * * * *```

We use single for-loop and in the loop we maintain two variables for line count and current star count. If current star count is less than current line count, we print a star and continue. Else we print a new line and increment line count.
