Solution 1 (Variables) Let be the median. It follows that the two largest integers are both. Let and be the two smallest integers such that The sorted list is Since the median is greater than their arithmetic mean, we have or Note that must be even. We minimize this sum so that the arithmetic mean, the median, and the unique mode are minimized.The first link contains the full set of test problems.
