#The goal of this exercise is to convert a string to a new string where each character 
#in the new string is "(" if that character appears only once in the original string, 
#or ")" if that character appears more than once in the original string. 
#Ignore capitalization when determining if a character is a duplicate.
#Examples
#"din"      =>  "((("
#"recede"   =>  "()()()"
#"Success"  =>  ")())())"
#"(( @"     =>  "))((" 
#Notes
#Assertion messages may be unclear about what they display in some languages. 
#If you read "...It Should encode XXX", the "XXX" is the expected result, not the input!
