如上图所示,刚开始base指针和tZ喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcNa41eu2vNa4z/LVu7XNo6y1sdG51bu1xMqxuvKjrHRvcNa41evP8snP0sa2r6Os1rG1vdW7wvq686Os1bu2pda41et0b3DWuM/y1bvN4rXY1rejrLTLyrHO0sPH0OjSqtTZt9bF5NDCv9W85KGjPC9wPjxwPjwvcD48cHJlIGNsYXNzPQ=="brush:sql;">#include 上面的conversion函数是一个将10进制转换为8进制的例子,这个就是栈的一个应用,还有例如,括号匹配的验证、迷宫求解等。 例如Hanoi塔问题: 假设有3个分别为a,b,c的三个塔座,a上有直径从大到小的圆盘,可以借助b塔座将a上的圆盘移动到c上,移动过程中大小顺序不变。void movePic(char a, int n, char b){
printf("将编号为%d的圆盘从%c上移动到%c上\n", n , a, b);
}
void hanuota(int n, char x, char y, char z){
if(n == 1){
movePic(x, 1, z); //将编号为1的圆盘从x移到z
}else{
hanuota(n - 1, x, z, y); //将x上编号为1到n-1的圆盘移到y,z作辅助塔
movePic(x, n, z); //将编号为n的圆盘从x移到z
hanuota(n - 1, y, x, z); //将y上编号为1到n-1的圆盘移到z,x作辅助塔
}
}
int main(){
hanuota(3, 'a', 'b', 'c');
}
1、要将n个圆盘移动到c,则需要先将n-1个圆盘移动到b
2、再将a上的最底下的圆盘移动到c
3、最后将b上面的n-1个圆盘移动到c
经过这三个步骤就可以完成移动,在这三个步骤中,步骤1,从a将n-1个圆盘移动到b和问题本身是同一个问题,步骤3将n-1个圆盘从b移动到c也和问题本身是同一个问题,所以这两处我们就可以迭代调用。

When using complex data structures in Java, Comparator is used to provide a flexible comparison mechanism. Specific steps include: defining the comparator class, rewriting the compare method to define the comparison logic. Create a comparator instance. Use the Collections.sort method, passing in the collection and comparator instances.

Based on the continuous optimization of large models, LLM agents - these powerful algorithmic entities have shown the potential to solve complex multi-step reasoning tasks. From natural language processing to deep learning, LLM agents are gradually becoming the focus of research and industry. They can not only understand and generate human language, but also formulate strategies, perform tasks in diverse environments, and even use API calls and coding to Build solutions. In this context, the introduction of the AgentQuest framework is a milestone. It not only provides a modular benchmarking platform for the evaluation and advancement of LLM agents, but also provides researchers with a Powerful tools to track and improve the performance of these agents at a more granular level

1. Click [System Management] in the phone settings menu. 2. Click the [Language] option. 3. Select the system language you want to use.

1. Code specifications during background reconstruction work: During the B-end front-end development process, developers will always face the pain point of repeated development. The element modules of many CRUD pages are basically similar, but they still need to be developed manually, and time is spent on simple element construction. This reduces the development efficiency of business requirements. At the same time, because the coding styles of different developers are inconsistent, it makes it more expensive for others to get started during iterations. AI replaces simple brainpower: With the continuous development of large AI models, it has simple understanding capabilities and can convert language into instructions. General instructions for building basic pages can meet the needs of daily basic page building and improve the efficiency of business development in general scenarios. 2. Generate link list. B-side page lists, forms, and details can all be generated. Links can be roughly divided into the following categories:

Data structures and algorithms are the basis of Java development. This article deeply explores the key data structures (such as arrays, linked lists, trees, etc.) and algorithms (such as sorting, search, graph algorithms, etc.) in Java. These structures are illustrated through practical examples, including using arrays to store scores, linked lists to manage shopping lists, stacks to implement recursion, queues to synchronize threads, and trees and hash tables for fast search and authentication. Understanding these concepts allows you to write efficient and maintainable Java code.
