1015 theory of virtue and talent (25 points) Sima Guang, a historian of the Song Dynasty, wrote a famous "theory of virtue and talent" in Zizhi Tongjian: "therefore, the perfection of talent and morality is called a saint, the death of talent and morality is called a fool, the victory of virtue is called a gentleman, and the vic ...

In the previous section, we have learned about continuous storage in linear storage. We also call this storage structure sequential table or array. We also know that linear continuous storage has the following advantages and disadvantages: Advantages: it can quickly add and access elementsDisadvantages: inserting or deleting elements will mo ...

1. Fibonacci sequence Title Description Fibonacci numbers are usually represented by F(n), and the sequence formed is called Fibonacci sequence. The sequence starts with 1 and 1, and each subsequent number is the sum of the first two numbers. That is: F(0) = 1，F(1) = 1 F(n) = F(n - 1) + F(n - 2), where n > 1 Here you are n, please calculat ...

To realize the game, we must first think about the principle and layout of the game. First, let's take a look at the board and rules of the game. The computer (randomly) and the player play the next game at a time, and the two sides take turns until either of the computer and the player wins, or the chessboard is full, and the game ends. Wi ...

1 Arbitrary input of three integers, programming to sort the three integers from small to large. Implementation process: (1) Define the data type. In this example, a, b, c and t are all basic integers. (2) Use the input function to obtain any three values and assign them to a, b and c. (3) Use the if statement to make conditional judgment. ...

Title Description:    give the charge (cents/minute) of each hour interval in 24h, and give N call recording points. Each call recording point records the name, current time (month: Day: hour: minute) and whether it belongs to on-line or off-line. Now it is necessary to calculate the tariff of each person's effective call records. Eff ...

With the help of page table mechanism and interrupt exception handling mechanism, this experiment completes the implementation of page fault exception handling and fifo page replacement algorithm. ucore established mm_struct and vma_struct data structure, which describes the legal memory space required by ucore simulation application. vma_ The ...
