Problem Statement

Take a string and repeat it some number of times.
Example: repeat("ha", 5)   =>   "hahahahaha" If there is a simpler/more efficient way to repeat a single “character” (i.e. creating a string filled with a certain character), you might want to show that as well (i.e. repeat-char("*", 5) => "*****").

Let's start with the solution:

def rep  /# s n -- s #/
     "" swap
     for drop
	over chain
     endfor
     nip
enddef

"ha" 5 rep print

65 5 rep
65 5 repeat
'A' 5 repeat
