The implementation also has a neat trick. In cases where the size of the original buffer is big enough, the trailing bytes of the buffer can be set with a single (possibly unaligned) store operation. The end address of the buffer is computed, and 8 (or 16) bytes is subtracted from it...
The entire structure appears to be a baseclass with virtual functions, which can be implemented differently for various purposes in a derived class. However, this is unrelated to the usage ofmemset. Solution 2: While memset can be used in C++, if you prefer the conventional C++ approach to ...
Implement a data structure, provide two interfaces: add(number). Add a new number in the data structure. topk(). Return the top k largest numbers in this data structure. k is given when we create the data structure. top之间比最弱, 用min heap. add O(logk) topk O(klogk) 但是kth la...
