You can easily adapt this code to your specific sorting requirements by modifying the conditions inside the operator() function within the sortCri struct.
you can either sort with a specialised comparison function in a one-hit sort, or you can sort hierarchically. This can be beneficial when the order of items is less important for a subset of the whole range. The render queue is still a good example. If you split your sort into different...
If you refactor like in the last section, you will not need operator(), or a struct at all—again, just map the projected inputs into a std::vector and call your in-place-sort overload on that. Refactoring your insertion-sort into a separate function is a good idea, and that helpe...
The std::sort function is commonly used to sort a vector in C++. By default, it sorts the elements in ascending order, and it modifies the original vector. Example Here's the C++ code to sort a vector using std::sort. We call std::sort(v.begin(), v.end()) to sort the vector ...

that uses a call-back function. The overhead of that function call makes it 2-3X slower than the C++ template functions in this library where the comparison function call is usually inlined by the compiler. For these reasons, it is difficult to recommend the C-libraryqsort()function. ...
Let us see sorting a string using C++ STL library that is sort() function which is provided by the library in C++ which is included in <algorithm> header. Example: #include<bits/stdc++.h> using namespace std; void StringSort(string &str1) ...
In short, I have a vector<vector<int>>a(n); The sort function is sort(a.begin(),a.end(),[&](autoa1,autoa2){return(a1.back()<a2.back());}); Instead of sorting, create a map to store the position of albums with each maximum coolnesspass ...
