#Write a function, perishable, that has one parameter - number of items in 
#the store. The function reads the barcode (integer number) for each item 
#and its price (floating number). All perishable items in the store have 
#EVEN barcodes. The function finds and returns the number of PERISHABLE 
#items that cost under 2 dollars.

#Write main that reads the number of items in the store, calls function 
#perishable to find the number of PERISHABLE items that cost under 2 
#dollars. If there are NO such items, the program prints appropriate 
#message.
