Ex Input:
Wrigleys' 5 FLARE sugarless gum is Wrigleys' sugarless replacement for their "Big Red" cinnamon gum. 5 flare seems to be difficult to find in stores. Thanks to Amazon I always have a supply. 5 FLARE is also the longest lasting gum I have ever experienced both in flavor and durability. It is positively the best cinnamon flavor currently on the market.

Ex Output:
5


Ex Input:
I would not order these K-cups again.  Maybe I'm spoiled with Godiva hot chocolate, but I think Swiss Miss hot chocolate has more chocolately flavor than these K-cups and I wouldn't waste my money on these.  It comes out a pinkish color that is not appetizing at all.

Ex Input:
The best potato chips I've ever had at the best price I've ever paid. The service was respectable and the shipping free.
