题目类型:位运算 传送门:>Here< 题意:求区间\([L,R]\)内二进制中1的个数最多的那个数,如果有多解输出最小解 解题思路 想了15min就一遍A了 我们可以贪心地在\(L\)的基础上+1,从小的往大的加.根据二进制的性质,我们不可能把原来的1变成0,除非在更高位搞出一个新的1来.因为如果不在更高位搞出一个1,就肯定比\(L\)小了.而我们又不可能搞掉一个地位,去弄一个高位,因为这样不仅没有让1的个数增多,反而让数字更大了 因此我们的最优策略,就是从最低位开始给0的位补1.知道超过\…
Write a function that takes an unsigned integer and returns the number of ’1' bits it has (also known as the Hamming weight). For example, the 32-bit integer ’11' has binary representation 00000000000000000000000000001011, so the function should retu…

解剖SQLSERVER 第五篇  OrcaMDF里读取Bits类型数据(译) http://improve.dk/reading-bits-in-orcamdf/ Bits类型的存储跟SQLSERVER其他定长数据类型的存储很不一样.通常,所有定长列都会显示出来,一个条记录里定长数据部分的字段数据总是一个挨着一个 我们可以写入磁盘的最小数据单位是一个字节,存储位类型数据的天真的方法就是使用一整个(字节@)来存储每一个位,使用常用的格式去解释位类型数据是很简单的 ,不过这会浪费一些空间 ,就像nu…
