摘要：懒省事的小明时间限制：3000 ms | 内存限制：65535 KB难度：3描述 小明很想吃果子，正好果园果子熟了。在果园里，小明已经将所有的果子打了下来，而且按果子的不同种类分成了不同的堆。小明决定把所有的果子合成一堆。 因为小明比较懒，为了省力气，小明开始想点子了: 每一次合并，小明可以把两堆果子合并到一起，消耗的体力等于两堆果子的重量之和。可以看出，所有的果子经过n-1次合并之后，就只剩下一堆了。小明在合并果子时总共消耗的体力等于每次合并所耗体力之和。 因为还要花大力气把这些果子搬回家，所以小明在合并果子时要尽可能地节省体力。假定每个果子重量都为1，并且已知果子的种类数和每种果子的... 阅读全文
