1. hashtable结构 SGI STL中hash table使用的是开链法进行的冲突处理,hashtable的桶与节点,表格内的每个单元,涵盖的不只是节点(元素),还可以是一个桶节点。buckets的聚合体,是以vector完成,以便有动态扩充能力。 hash table的节点定义如下: [cpp] <span style="font-family:Micros...
第一步是将前10个元素复制到数组中。第二步是顺次排序您的10项数组,因此您将始终使用最后一项进行比较...

To pre-compile test.h, execute "g++ -O2 -Wall -x c++-header test.h -o test.h.gch" To compile test file, execute "g++ -O2 -Wall -include test.h primitivehashmap.h main.cpp" To run test file, execute "./test" The table is built using C++ primitive. Optimization is done by cho...
