C++C++ Operator In C++, bit shift operators do what their names suggest, shifting bits. According to the program’s requirements, a bitwise shift operator shifts the binary bits left or right. Integer values are applied to these operators (int, long, possibly short, and byte or char). In ...

几乎所有流行的编程语言(Java,C,C ++,Go,C#,Rust,Python……)都提供了 Roaring Bitmaps。 2. 主要思想 我们以存放 Integer 值的 Bitmap 来举例,RBM 把一个 32 位的 Integer 划分为高 16 位和低 16 位,通过高 16 位找到该数据存储在哪个桶中(高 16 位可以划分 2^16 个桶),把剩余的低 16 位放入该...
