:
One line with an integer n (1≤n≤1): The number of orders.
n lines of the form "Order_type x shares at Y", Whereorder_type are either "buy" or "sell", and X (1≤x≤1) is the number of shares of a-someone wishes to-buy or to sell, and Y (1≤y≤1) are the desired price.
Output
Per test case:
n lines, each of the form "Ai bi si", where ai, bi and Si are, bid and stock prices, respectively, after t He i-th the order has been processed and all possible deals
This chapter deals with some practical issues.
Statement delimiter
Some languages require a certain type of punctuation, typically a semicolon (;) to end each statement of the program. Ruby uses the shell's SH and csh convenience. Multiple statements in a row are separated by semicolons, but not at the end of a line; a newline is treated as a semicolon. If the line ends with a backslash (\), subsequent lines are ignored; This allows your individual
a = 3; Here's A is a reference to the int type,
Point to the literal value of 3. The value of the data, due to the size of the known, lifetime known (these literals are fixed in a program block, the program block exit, the field values disappear),
The reason for the pursuit of speed, is in the stack.
In addition, the stack has a very important particularity, is the existence of the stack of data can be shared. Let's say we both define:
int a = 3;int b = 3;

can be continuously invoked if the pointer constantly points to an object that is not homogeneous in the same class. It's like saying, keep telling the taxi driver where to go, and then the driver will send you to where you want to go.
It is necessary to note that a non-virtual function that is sometimes defined in a base class is redefined in a derived class (such as the area function in an example). If the member function is called with a base class pointer, the system calls the member funct

no follower moved out of the ISR. So the replica.lag.max.message setting seems reasonable.
But producer initiates instantaneous peak flow, producer send more than 4 messages a time, that is, more than replica.lag.max.messages, at this time follower will be considered to be and leader copy is not synchronized, and thus was kicked out of the ISR. But in practice these follower are alive and without performance problems. Then after catching up with leader, and was rejoin the ISR. So it appears tha

There are two things in life that will not change: death and the service charge of a bank. Today I'm going to make a clear explanation of the reason for the charge, the type and usefulness of the cost of the bit-unit system. On a higher level, in fact, there are two kinds of fees: the fixed costs defined by the agreement and the variable transaction fees determined by the trustee. In fact, a trustee can raise a fixed fee if he agrees, but not a fixed fee.

You can learn about classes, objects, threads, collections, and other language features such as generics, enumerations, mutable parameters, and auto-boxing. This book also deals with swing, network programming, IO operations in Advanced Java programming, which allows beginners to have a more complete con

For example, if the footer style requires only 20 lines of CSS code, creating a single file will not work. And this method will cause each page to contain a bunch of CSS files--because of how many include, how many CSS files.

For example, if you have a spa that usually costs 100 dollars per massage, is it a good idea to offer 1000 massage services at each price of 25 dollars? Or, if you own a restaurant with a meal of 30 yuan, would it be a good idea to sell 1000 packages at the price of 10 dollars per share?
