How do I merge two containers efficiently with std::set for embedded targets?

Merging two `std::set` containers efficiently in C++ can be accomplished using the `insert` method, which allows for seamless integration of elements while maintaining the properties of the set. This guide explores an optimized approach for merging sets, suitable for embedded target applications.

#include <iostream> #include <set> int main() { std::set set1 = {1, 2, 3, 4, 5}; std::set set2 = {4, 5, 6, 7, 8}; // Merging set2 into set1 set1.insert(set2.begin(), set2.end()); // Displaying the merged set for (const auto& elem : set1) { std::cout << elem << " "; } std::cout << std::endl; return 0; }
