Like all constructors, he is also a beer fan. He likes beer so much that has K cups of beer daily. However, having more than K cups doesn't suit him, because the excess beer won't allow him to sleep at night. Danish's working day is divided into N periods. For every period, he knows how many kilobytes of weight he can lift. During each of the periods, Danish can either have or not to have one bottle of beer. If he is having a bottle of beer in some period, the amount of work in this period drops to zero. But he also gets a productivity boost, if he decides to skip beer during a period and the last bottle of beer, he had was no more than D periods ago, the amount of work during such a period is M times the usual.
