    终于,破解了千年的难题。小FF找到了王室的宝物室,里面堆满了无数价值连城的宝物……这下小FF可发财了,嘎嘎。但是这里的宝物实在是太多了,小FF的采集车似乎装不下那么多宝物。看来小FF只能含泪舍弃其中的一部分宝物了……小FF对洞穴里的宝物进行了整理,他发现每样宝物都有一件或者多件。他粗略估算了下每样宝物的价值,之后开始了宝物筛选工作:小FF有一个最大载重为W的采集车,洞穴里总共有n种宝物,每种宝物的价值为v[i],重量为w[i],每种宝物有m[i]件。小FF希望在采集车不超载的前提下,选择一些宝物装进采集车,使得它们的价值和最大。

【输入格式】

    第一行为一个整数N和w,分别表示宝物种数和采集车的最大载重。

    接下来n行每行三个整数,其中第i行第一个数表示第i类品价值,第二个整数表示一件该类物品的重量,第三个整数为该类物品数量。

【输出格式】

    输出仅一个整数ans,表示在采集车不超载的情况下收集的宝物的最大价值。
