You are playing the popular card game “Inscribings”. In this game, your opponent places n monster cards onto the board, the ith of which has hi health points. You in turn have m ≥ n hero cards in your hand, the jth of which deals dj damage per turn. To begin the game, you will choose n heroes from your hand and assign each of them to a different enemy monster. Each turn, your heroes will deal damage equal to their damage power to the opposing enemy. If at any point an opponent’s monster reaches 0 health or less, then it is destroyed. You are given a limited number of turns k to destroy all enemy monsters. Design an algorithm which runs in O(m + n log n) time and determines whether it is possible to assign your heroes in such a way as to destroy all enemy monsters in k turns or fewer. If it is possible, your algorithm must also return any such assignment. Need an algorithm which runs in Θ(m log m) time.
