You are given a list of integers and a value "n". Your task is to identify the integers greater than "n" and find their sum. Then, subtract the minimum value of this subset from the sum to obtain a preliminary result. Multiply the count of these integers with the average value of the entire list and then subtract this ... | codefeedback | [
