user: ## Task:

You have to write a function `pattern` which returns the following Pattern(See Examples) upto desired number of rows. 

* Note:`Returning` the pattern is not the same as `Printing` the pattern.

### Parameters:
    
    pattern(        n        ,        x        );
                    ^                 ^         
                    |                 |         
             Term upto which   Number of times  
              Basic Pattern     Basic Pattern   
                should be         should be     
                 created          repeated      
                                horizontally    
    
* Note: `Basic Pattern` means what we created in [Complete the pattern #12]("http://www.codewars.com/kata/558ac25e552b51dbc60000c3")
### Rules/Note:

* The pattern should be created using only unit digits.
* If `n < 1` then it should return "" i.e. empty string.
* If `x <= 1` then the basic pattern should not be repeated horizontally.
* `The length of each line is same`, and is equal to the length of longest line in the pattern.
* Range of Parameters (for the sake of CW Compiler) :
  + `n ∈ (-∞,50]`
  + `x ∈ (-∞,25]`
* If only one argument is passed then the function `pattern` should run as if `x <= 1`.
* The function `pattern` should work when extra arguments are passed, by ignoring the extra arguments.
   
   
###Examples:

* Having Two Arguments-
