C++ 坑 记录 受到Python的影响 我写出了如下代码

if (a <= b <= c)

然后这代码并不像Python那样执行 而是这样执行

(a <= b) <= c

comwrg

C#, keyword await and async. What order of execution ?

Console.WriteLine("BLOCK A"); // BLOCK A
Task task = Task.Delay(1000); // BLOCK B
Console.WriteLine("BLOCK C"); // BLOCK C
await task; // BLOCK D
Console.WriteLine("BLOCK E"); // BLOCK E

1. 计算测试样本和每一个训练样本的距离 (原理: 欧式距离)
2. 将距离进行排序, 距离越小, 说明测试样本和训练样本越相似
3. 取前K个距离所对应的样本数据, 最后取样本数据数量最多作为结果
