Duplicate a character 'n' times.
Example 1: str='a' n=5
output='aaaaa'
Example 2: str='*' n=3
output='***'
n is a nonnegative interger.may it be the largest problem that i meet.
My initial solution with repelem(str,n) for n=0 creates a size 1x0 char class but suite only allows for a 0x0 class. Not sure why the difference would matter.
