黑红树(Red-Black tree),在英语口语交流中我们通常将其称为 “Red-Black tree”。当我们解释这个概念时,可以说 "Red-Black tree is a type of self-balancing binary search tree where each node has an extra bit for denoting the color of the node, either red or black…”。 黑红树是一种自平衡的...
The reason why we have to provide a sorting rule for user-defined classes as keys is because std::map is a binary search tree data structure. This video shows how binary search trees work in general . Binary search trees store their data in sorted order, thus we have to ...
/// the amount of work performed in a search. In theory, a binary search tree (BST) is the optimal /// choice for a sorted map, as a perfectly balanced BST performs the theoretical minimum amount of /// comparisons necessary to find an element (log2n). However, in practice the...

The keys must be unique, and the container uses a binary search tree internally for optimal performance. 2. STL Algorithms: 2.1. std::sort: std::sort is a widely used algorithm to sort elements in a container. It utilizes efficient sorting techniques, such as QuickSort or HeapSort, to ...
std::map is usually implemented as a binary search tree. http://en.wikipedia.org/wiki/Binary_search_tree This is an example of a binary search tree. I'm using numbers instead of strings to make the ordering more obvious but the principle is the same for strings. Notice how the numbers...

there a way to tell the std::set to check the end of the tree before doing the insert as a fast check on where the key is going to end up ? RTFM. There is more than one 'insert' function. Also see the return values of those 'insert' members. ...
