Simple binary search in a vector - Code Review Stack …
WebIn the binary search() function, we modify it and pass a fourth argument, a call to a user-defined explicit function. This function compares the searching value to the first element of pairs found in pair vectors. Pseudocode Declare a structure keycompare Function operator()(const pair& v, const int& k) status = v.first < k. WebMar 13, 2024 · If were aiming at a vector with pairs: you could the elements of the vector and use find to find elements. But this is a binary search, and will practically be as fast as a std::map. Anyway, try to model the data in the obvious manner. Premature optimization often doesn't help much.
