1. The problem statement, all variables and given/known data Lets say we have two strings 'movies' and ' goto'. Now the question indicates to return this combination concatenated n times, except if n is negative, it is the same as if it were 0. 3. The attempt at a solution Concatenation n times would yield: n*"movies goto" Now if n is negative it performs in the same way you would expect 0 to perform, so would that just return None ? Like if n = 0, or n = -4 should it just return None?
