In the sport of diving, seven judges award a score between 0 and 10, where each score may be a floating-point value. The highest and lowest scores are thrown out and the remaining scores are added together. The sum is then multiplied by the degree of difficulty for that dive. The degree of difficulty ranges from 1.2 to 3.8 points.

The total is then multiplied by 0.6 to determine the diver's score. Need a computer program that inputs a degree of difficulty and seven judges' scores and outputs the overall score for that dive. The program should ensure that all inputs are within the allowable data ranges.
