Milline on operatsiooni aja keerukus, kui eemaldada element assotsiatiivsest konteinerist map?

In the standard implementation of an associative container map (for example, in C++ STL), a balanced tree (usually a red-black tree) is used. The time complexity of removing an element from such a map is O(log n), where n is the number of elements in the container.

This is because, to remove, you first need to find the element (logarithmic time), and then perform the restructuring of the tree, which also occurs in logarithmic time.
