Given an array consisting of n integers, find the contiguous subarray of given length k that has the maximum average value. And you need to output the maximum average value. Example 1: Input: [1,12,-5,-6,50,3], k = 4 Output: 12.75 Explanation: Maximu…
We partition a row of numbers A into at most K adjacent (non-empty) groups, then our score is the sum of the average of each group. What is the largest score we can achieve? Note that our partition must use every number in A, and that scores are not…
输入大于五的人数成绩,去掉两个最高分,和两个最低分,求其平均数. Console.Write("请输入人数"); int renshu = int.Parse(Console.ReadLine()); int[] chengji = new int[renshu]; if (renshu >= 5) { for (int h = 1; h <= renshu; h++) { Console.Write("请输入第" + h + "个人成绩&qu…
重视Code Review 极致--目标是成为优秀的开发者 Data tells a story!(数据会讲故事) 分析过程对于建模非常的重要,可以帮助我们减少实际上不相关的特征被错误的加入到模型中,尽管在一些模型里,比如线性回归,在建模后期可以通过一定的方法将这些不相关的特征识别出来,但既然能够通过前期的数据观察排除,何不在一开始就做好呢,有句话在建模领域非常有名:garbage in, garbage out 数据的中心:众数.平均数和中位数 要点:模型构建&验证比较模型 一.Why? 为什…
