int minValue(string a, int k){ unordered_map<char,int>mp; //O(n) for(int i = 0;i < a.size();i++) mp[a[i]]++; priority_queue<int>q; //O(n*logn) in worstCase for(auto i : mp) q.push(i.second); //O(k * log(n) while(k && a.size() > 0) { int p = q....
This happens often, even when there is a significant difference in time complexity, such as O(N) and O(N^2). If you want to know where the time complexity of hashmap, especially the unordered_map of C++, has a big constant, check the following videos and links....

DirectX 11引进了一种缓存类型,允许访问任一位置像素的值,该功能叫做UAV(unordered access view)。这个功能一开始只有像素着色器和compute shader可以用,到DirectX 11.1这里,所有的着色器都可以使用UAV功能。Opengl 4.3称这个功能为SSBO(shader storage buffer object)。两个名字都用他们自己的方式解释了这个功能。像素着...

The drawback of space-time trellis codes is that for larger numbers of antennas to achieve full diversity requires the encoder to have longer memory (a longer shift register), and the trellis to contain exponentially more states. Since decoding complexity is proportional to the number of trellis...

This allows you to enrich the stream events asynchronously, so it can send a request for other elements in the stream while it waits for the response for the first element and requests can be batched for greater efficiency. While using this pattern, you have to decide between unorderedWait ...
A real-time motion capture system is presented which uses input from multiple standard video cameras and inertial measurement units (IMUs). The system is a
