state of electronic equipment is generally used to save the stack, often the computer out of trouble when it will say what stack overflow, is such a problem.Queues are also common, let's say, we go to the cafeteria to eat. On the line, first-out structure.His homework is to be able to operate on a fair basis. ps:1197: Egg queueSo how do you use such a structure?Note that they are actually linked lists, but the operation of the numbers is limited.

Test instructions: Give you a set of n number, choose two delete each time, put them and put back to the collection, until the number of the set is only one, the cost of each operation is that two number of the and, the minimum cost.The Huffman Code of Red fruit fruit.

Open-drain and Push-pull "The function of Gpio is simply that it can be configured as input or output according to its own needs. However, when configuring the Gpio pins, two modes are often seen: open-drain (open-drain, open-drain) and push-pull (push-pull).What are the differences between the two modes, and the following collated some information to explain in detail:Chart 1 push-pull contrast Open-drain Push-pull Push-Pull output Open-drain Open-Drain output

. The algorithm behind the directional switch is simple?? The message is pushed to: Message routing key and queue binding key exactly match the queue. To illustrate, consider the following setup: To clarify, think about the following structure: In this setup, we can see the direct Exchange X with a queues bound to it. The first queue is bound with binding key orange, and the second have both bindings, one with binding key Blackand the other One with green. On this structure, we can see tha

Title: Existing two incremental single-linked list L1 and L2, design an algorithm to merge all nodes of L1 and L2 into the incremented single-linked list L3. Requirements: Space complexity is O (1).Ideas: The topic can be used in two ways to merge ideas, but the title requires space complexity of O (1), so can not replicate nodes, can only destroy L1 and L2 to insert nodes into the L3.Code:voidMerge (linklistL1,linklistL2,linklistL3) {linklist*P=L1.Head -Next*Q=L2.Head -Next Linklist*P1,*

result set Q1.

If yes, the record is retained. If no matching exists, this row is ignored, then retrieve the next record from
