( 712 ) E Awards For Contestants PROGRAMMING brute force data structures dp 2500

B"Alexey recently held a programming contest for students from Berland. n students participated in a contest, i-th of them solved ai problems. Now he wants to award some contestants. Alexey can award the students with diplomas of three different degrees. Each student either will receive one diploma of some degree, or won't receive any diplomas at all. Let cntx be the number of students that are awarded with diplomas of degree x (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89x xe2 x80 x89 xe2 x89 xa4 xe2 x80 x893). The following conditions must hold: Of course, there are a lot of ways to distribute the diplomas. Let bi be the degree of diploma i-th student will receive (or xe2 x80 x89- xe2 x80 x891 if i-th student won't receive any diplomas). Also for any x such that 1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89x xe2 x80 x89 xe2 x89 xa4 xe2 x80 x893 let cx be the maximum number of problems solved by a student that receives a diploma of degree x, and dx be the minimum number of problems solved by a student that receives a diploma of degree x. Alexey wants to distribute the diplomas in such a way that: Help Alexey to find a way to award the contestants! The first line contains one integer number n (3 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x893000). The second line contains n integer numbers a1, xe2 x80 x89a2, xe2 x80 x89..., xe2 x80 x89an (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89ai xe2 x80 x89 xe2 x89 xa4 xe2 x80 x895000). Output n numbers. i-th number must be equal to the degree of diploma i-th contestant will receive (or xe2 x80 x89- xe2 x80 x891 if he doesn't receive any diploma). If there are multiple optimal solutions, print any of them. It is guaranteed that the answer always exists. "...
