The title means: an N-node apple tree, each node has a certain number of apples; Ask from 1 to go to the apple that can be late for K-step (each step can only go to adjacent nodes)Solution:The following basic conditions are included in the walk (the other methods can be combined by the following):1: On the tree is not back on the forward;2: Go back to the node you walked over to another node:So for each node there is a flag gone and not come back? Or walked by and came back!The other is the back

protocol for Processing Based on the Type field. Save the destination MAC address and source MAC address for subsequent use.
According to 802.3, the Ethernet Type field (ethertype field) is two octal fields. In quantitative evaluation, the first eight-byte field is the most important. When the field value is greater than or equal to the decimal value 1536 (that is, the hexadecimal value is 0600), The ethertype field represents the type of the Mac client protocol (ethertype interpretation.

1. Why does the bypass function be required?
Applications of various types of gateway devices connected in the network will process some data packets through the gateway device, and then forward the packets after processing, if the gateway device becomes a single point of failure due to unexpected failure (such as hardware failure, power failure, or software deadlock), the customer's network will be paralyzed. To avoid this situation, bypass devices become an inevitable solution.
2. What are the
First, download a version from the FFMPEG official website and select a version under the "FFMPEG releases" column:
Http://ffmpeg.org/download.html
Then, decompress the package directly. Open the terminal of OS X and run the CD command to enter the project directory.
If your OS X uses the latest version of xcode 4.3.x or later, all compilation tools are displayed in sandbox status, that is, they are not registered to the system environment, therefore, you cannot directly compile data using
After the application is developed and enters the testing stage, you usually need to release some internal versions to the tester's machine for installation. How to do this? This article will introduce in detail.
1. If the user's machine has been jailbroken, it is easy to package it into IPA. the user can directly install it through tools such as 91 assistant, synchronous push, and PP assistant.
2. If the user's machine is not jailbroken, the following solutions are available:

IOS development and learning processThe following is a brief introduction of how I feel about iOS development. It is also an architecture for learning iOS development. 1 iOS development environment 1.1 The standard configuration of the development environment is Mac OS X + Xcode. Macbookpro is the preferred choice for maccosx. macmini is the cheapest as long as it is more than 4000 yuan, and then it should be equipped with a display. macbookpro is also acceptable. macbookair is not recommended.
It's quite troublesome. Let me talk about the general process:
You must have a Visa credit card that supports international payment.
Go to the Apple developer website and register an account. This step is free of charge.
Then log in and click enroll to enter a process and enter the development plan, personal information, and credit card information you want to join. Because China does not support direct payment, this process will give you a PDF form, print and fill out the signature, scan and
