appears at this position; what if it doesn't wait? It depends on whether it is equal to the prest. If it is equal, it indicates that this number can be obtained by going into the stack and then going out of the stack. Then there is no problem with this number in this position. If it is different from PST and Prest, this number is generated in the wrong position.
In fact, it is spread from the center to the left and right sides to see if it is equal to the number of boundaries. This is the case.

Overview
Previously studied PHP input and output buffer, but after the blog moved, the original article can not find, today saw a good article, by the way reproduced over.
Brief introduction
When it comes to output buffering, the first thing to say is something called a buffer (buffer). A simple example illustrates his role: when we edit a document, the system does not write to the disk until we save it,
When it comes to output buffering, the first thing to say is something called a buffer. Give a simple example of his role: when we edit a document, the system does not write to the disk until we have saved it, but writes it to buffer and writes the data to disk when buffer is full or a save operation is performed. For PHP, each time an output like Echo is written to PHP buffer, the data is displayed on the

Push-pull output: outputs high and low levels and connects to digital devices;
Open-drain output: the output end is equivalent to the collector of the transistor. To obtain a high-level state,

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

When outputting data, for simplicity, the format of the output is often not specified, and the system takes the default format based on the type of data, but sometimes you want the data to be output in a specified format, such as requiring that an integer be output in 16 or octal, and only two decimal places are reserved for the small number of the
