The scoring rules are as follows: a total of N judges give scores (0-100 points), one of the highest score and one of the lowest score is required to be removed, and the average score of the remaining scores is the final score. Enter a positive integer repeat (0 < repeat < 10) and perform the following operations:
Input a positive integer n (3 ≤ n ≤ 10), which means there are n judges, input n scores, output the final score, and reserve two decimal places of the result.
