How do I merge and splice sequences with std::multiset?

This article provides an overview of how to merge and splice sequences using the std::multiset in C++. Learn techniques for efficiently managing sorted data collections.

// Include necessary libraries #include <iostream> #include <set> int main() { // Create two multiset containers std::multiset set1 = {1, 2, 2, 3, 4}; std::multiset set2 = {2, 3, 5, 5}; // Merging the two multisets std::multiset mergedSet; mergedSet.insert(set1.begin(), set1.end()); mergedSet.insert(set2.begin(), set2.end()); // Output merged multiset std::cout << "Merged Set: "; for (int num : mergedSet) { std::cout << num << " "; } std::cout << std::endl; // Splicing (moving elements from one multiset to another) std::multiset spliceSet; spliceSet.insert(mergedSet.extract(mergedSet.find(3))); // Remove one '3' spliceSet.insert(mergedSet.extract(mergedSet.find(5))); // Remove one '5' // Output after splicing std::cout << "After Splicing (Splice Set): "; for (int num : spliceSet) { std::cout << num << " "; } std::cout << std::endl; return 0; }
