Study the algorithmic features of searching for elements in the std::map container and its time indicators.

std::map in C++ is implemented as a balanced binary search tree (usually a red-black tree). This provides the following search features:

• Searching for an element by key is performed in O(log n) time, where n is the number of elements in the container.
• Insertion and deletion also have a complexity of O(log n).

Thus, std::map is suitable for cases where ordered access and logarithmic operation complexity are important. If a faster key search operation without ordering is needed, consider std::unordered_map, which operates on average in O(1).

Example of search:

std::map<int, std::string> m;
m[10] = "ten";
auto it = m.find(10);
if (it != m.end()) {
    std::cout << it->second << std::endl; // Will output "ten"
}
