#ok, here’s my perhaps inelegant solution, and hi, I’m Kyle.

input=gets("\n")  
input.downcase!  
input.gsub!(/[^a-z+=]/,’’)  
left=input.split("==").first.split(’+’)  
right=input.split("==").last.split(’+’)  
exit(1) unless right.length==(right-left).length  
class String  
def ==(i)  
if super(self.split(’’).sort.join)  
return(super(i.split(’’).sort.join))  
else  
return(self.split(’’).sort.join==i.split(’’).sort.join)  
end  
end  
end  
left=left.join  
right=right.join  
success=(left==right)  
exit(1) unless success  
puts success  
exit(0)

Well, it solved a different part of the problem, but was still neat  
to see.
