首先,对于这题我们要知道要删除一个数使平均值最大一定是删除最小的数,然后我们假设删除操作执行了i次,也就是删除最小的i个数.在已知删除操作次数之后求增加操作的次数就容易了,当然是m - i和k * (n - i)中比较小的数啦.用一个ans变量记录结果,遍历i,更新ans,得到最终的ans. B - Average Superhero Gang Power GNU C++11 Accepted 46 ms 400 KB #include "bits/stdc++.h" using na…
A sequence a1,a2,-,an is called good if, for each element ai, there exists an element aj (i≠j) such that ai+aj is a power of two (that is, 2d for some non-negative integer d). For example, the following sequences are good: [5,3,11] (for example, for…
