Red Packets are a very popular thing recently. If you send or receive red packets more or less, let's look at a php program algorithm that we often encounter in our daily life, hope this program Red Packets are a very popular thing recently. If you

Use PHP to send red envelopes, when we enter the number of red envelopes and the total amount, PHP will be based on these two values to randomly allocate each amount, to ensure that everyone can receive a red envelope, each red envelope amount of

About RB TreesThe red and black tree is a binary search tree, which adds a storage bit on each node to represent the color of the node, which can be red or black. By constraining any color from the root to the leaf's simple path, the red-black tree

I. Red/black tree Overview Similar to the AVL tree we have learned before, the red and black trees maintain a balance between the binary search trees through specific operations during insertion and deletion operations to achieve high search

Recent projects need to chat on the basis of the new red envelope function, demand: imitation micro-letter (excluding messages), but only use the balance of red envelopes. So many times using the micro-letter red envelopes to understand the various

The red-black tree is Another variant of the AVL tree, and he can also maintain a sense of balance in the process of dynamic change, and the worst case scenario for a red-black tree is only the complexity of $o\left (\log n \right) $ , and below

The red and black trees in the introduction to algorithms are described as follows, which are similar to the four in STL source code analysis.1. Each node is either red or black.2. The root node is black.3. Each leaf node (NiL) is black.4. If a node
