Modify if statement (#36088)

Browse Source 
* Modify if statement

Change the solution so an empty string is returned when num is less than 1 rather than less than 0 for consistency with instructions.

* Add test 

New test checks that if num is 0, an empty string is returned

* Fix test 

Fixing errors in newly proposed test that checks that empty string is returned when num is 0

* Modify intermediate solution

Changing if statement in intermediate solution to check whether num is less than 1 rather than less than 0. (Also adding curly brackets to that solutions if/else statements.)

* fix: removed unnecessary assert message arguments
