the employees have decided to kill some time by creating some unique backstories for some of the critters in your park. partly due to their solitary nature there is not a more rich, diverse, and mysterious set of characters than that of your orangutans. to help distinguish between the different orangutans each one gets a name. due to the escapades that the orangutans get into their names can change from day to day. this dynamic element makes keeping track of the storylines tricky. the employees like to feed their favorite orangutans mangos as a treat. due to certain great ape weight issues, you are concerned that your employees may be over feeding some orangutans and underfeeding others. luckily, your employees track the orangutans that get fed. unluckily, your employees write the name of the orangutan at the time of the feeding. you have decided to embrace the nonsense that is an inconsistent and changing naming convention, but you have forced your employees to write down when an orangutan changes its name. you will focus on asking at particular times how many mangos have been eaten by the orangutans whose name begins with a particular letter sequence.
