Under this method, unless the nuggets to a new bag, otherwise employees received the first gold always be employees than t He second-nuggets. If There is a new cyclical nuggets joined bag, every month to find the lightest and most of the nuggets. Assuming that there are a comparison of weight machines, we hope thatAt least by comparisonTo identify the number and the lightest weight of gold. (The title description is not translated, in short, the meaning is to find the largest element and the smallest element in the array, there is a requirement that the least number of comparisons) Inputtwo lines
The first line was a number of gold nuggets and less than 50000
The second line is weight of every gold nugget. Outputtwo numbers
The first is weight of the heaviest nugget
The second is weight of the lightest gold sample Input65 2 7 6 3 4 Sample Output7 2 Hintsourcemryang

Note: Two number comparison, then that large number, it is impossible to be the smallest number in this group, the same, the small number, it is impossible to become the largest number of the group. From the usual 2*n comparison, it becomes the (N/2) *3=1.5*n comparison.
