dp_cache_.insert(make_pair(sentence, result)); } } And the types: typedef pair<float, vector<int>> segmentation; concurrent_unordered_map<string, segmentation> dp_cache_; I tried concurrent_hash_map and different versions of tbb or pre-built binaries. They all crashes. Any...

在ycf303(以下简称y神)的答案中第一次接触到unordered_map这一结构。 unordered_map是C++11特性,利用hash表实现,查找效率极高。 y神代码如下: 1classSolution {2public:3vector<double> calcEquation(vector<pair<string,string>>equations,4vector<double>& values, vector<pair<string,string>>query)5{6unordered...
