You are hired by a retail chain as a data miner. Suppose themanager is interested only in frequent patterns (itemsets) with oneof the following constraints:
a. The sum of the price of all the items (in each pattern) isbetween $100 and $200.
b. The price difference between the most expensive item and thecheapest one in each pattern must be less than or equal to$100.
c. The average price of all the items in each pattern is less than$10.
