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

In C++, merging and splicing sequences can effectively be achieved using the `std::vector` container, which is part of the Standard Template Library (STL). Merging involves combining two or more vectors into one, while splicing enables the insertion of elements from one vector into another at a specified position.

Merging Vectors

To merge two vectors, you can utilize the `insert()` method along with the `begin()` and `end()` iterators. Here’s an example illustrating how to do this:


    #include <iostream>
    #include <vector>

    int main() {
        std::vector vec1 = {1, 2, 3};
        std::vector vec2 = {4, 5, 6};

        vec1.insert(vec1.end(), vec2.begin(), vec2.end());

        for(int num : vec1) {
            std::cout << num << " ";
        }
        return 0;
    }

Splicing Vectors

Splicing involves inserting one vector's elements into another at a specified position. Here's how to do it:


    #include <iostream>
    #include <vector>

    int main() {
        std::vector vec1 = {1, 2, 3};
        std::vector vec2 = {4, 5, 6};

        // Splicing vec2 into vec1 at position 1
        vec1.insert(vec1.begin() + 1, vec2.begin(), vec2.end());

        for(int num : vec1) {
            std::cout << num << " ";
        }
        return 0;
    }
