Example Input: I loved this mold! I wished I could have used it for more than one occasion, but it didn't last. I did use it to make 30+ suckers for my daughter's first birthday. But there was going to be no way that the mold could be salvaged after that. I would have liked to have kept to use on other occasions, but for the price it didn't matter to me that much. It served it's main purpose :)
Example Output: 4

Example Input: Halloween is over but, I sent a bag to my daughters class for her share. The chocolate was fresh and enjoyed by many.

Example Input: I must be the odd man out here...but this powdered goat milk is horrible! My 18 month old son is allergic to dairy and soy, hence the reason for goat milk. We were going on vacation for two weeks, and I was afraid there would not be any source of goat milk at that destination. Being he drinks almost a quart a day of regular liquid goat milk I purchase from Trader Joe's, I figured I would go for the gusto and buy a two weeks supply for him. It smelled horrible and more importantly tasted horrible! Words cannot even describe how disgusting this stuff was. My poor son almost threw up from tasting it which prompted me to smell it. It smelled so bad, I couldn't even taste it myself. Maybe we're just used to the regular brand he drinks? My only advice, try a small amount first. It is not returnable!!!
