In worst case, on a 32-bit word with only the most significant bit set, it will loop through 32 iterations. This solution is the simplest one and useful if 1's are sparse and among the least significant bits. C program: iterative approach of counting set bits in an unsigned integer ...

数据库数据去重java java数据去重 数据去重除了对list循环之外一般会借助Set不包含重复数据特性来达到去重目的。 1、HashSet & LinkedHashSet 重写对象的hashCode和equals,优先判断hashCode返回值是否一样,一样再判断equals。HashSet无序(基于哈希表实现),LinkedHashSet有序(数据添加时的顺序),LinkedHash继承HashSet,均为...

SELECTyear,month,BIT_COUNT(BIT_OR(1<<day))ASdaysFROMt1 GROUPBYyear,month; 咋一看不太明白了,后来弄清了bit_or和bit_count函数的含义后就豁然开朗了。 bit_count函数的含义 用来计算二进制数中包含1的个数。 1 selectBIT_COUNT(10); 因为10转成二进制是1010,所以该结果就是2。
For each digit, create a bit representation. If the digit is d, then the bit representation is 1 << d. Use bitwise OR to updatemask. This marks the digit as seen. Count the number of bits set to 1 inmask. This count is the number of unique digits. ...
1 row in set (0.00 sec) 1. 2. 3. 4. 5. 6. 7. Rows:表中的记录条数。对于 MyISAM 存储引擎,该值是准确的;而对于 InnoDB,该值是一个估值。 Data_length:表占用的存储空间字节数。对于 MyISAM 存储引擎,该值就是数据文件的大小;而对于 InnoDB 引擎,该值就相当于聚簇索引占用的存储空间的大小。
