我的短信是这样的:
var text = `# Algorithms
This chapter covers the most basic algorithms.
## Sorting
Quicksort is fast and widely used in practice
Merge sort is a deterministic algorithm
## Searching
DFS and BFS are widely used graph searching algorithms
Some variants of DFS are also used in game theory app
我有以下规则:
/*The structure of a subject teaching team takes the form:
team(Subject, Leader, Non_management_staff, Deputy).
Non_management_staff is a (possibly empty) list of teacher
structures and excludes the teacher structures for Leader and
Deputy.
teacher structures take the form:

对于PHP和MVC概念,我还是个新手。我一直在尝试复制CI新闻教程(),同时使用我自己的数据库并重写代码。
我一直没有成功。
这是我的控制器:
class Main extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper('url');
$this->load->library('tank_auth');
$this->load->model(
谁能帮我加快这个刮擦过程,从instagram上的#‘猫’获取所有的用户名。我的目标是使这尽快,因为目前的进程有点慢。也许用多线程?
from instaloader import Instaloader
HASHTAG = 'cats'
loader = Instaloader(sleep=False)
users = []
for post in loader.get_hashtag_posts(HASHTAG):
if post.owner_username not in users:
users.append(post.owner_user
我试图在CLION中编译一个项目,但我无法成功,但我可以在Eclipse中编译完全相同的文件。首先,这是一个错误:
CMakeFiles\Besart.dir/objects.a(library1.cpp.obj): In function `Init':
C:/Users/Besart/ClionProjects/Besart/Data Structures 1/HW 2/library1.cpp:17:
undefined reference to `DataStructure::DataStructure()'
现在,我已经包含了所请求的文件,例如,在library1.
我安装了pear,并发现我在pear目录中有Structures_Graph目录-
/home/ec2-user/pear/tests
但是,我找不到中提到的Structures/Graph.php和Structures/Graph/Node.php
我一直在关注这篇文章,下面的Structures_Graph安装必须使用以下代码完成-
pear install Structures_Graph
我明白了-
pear/Structures_Graph is already installed and is the same as the released version 1.1.1

我在试着找出为什么我要尝试获取非对象的属性。我对对象和数组不是很熟练,但我正在努力。下面是代码和错误消息。对如何解决这个问题有什么想法吗?

我想以字符串的形式从变量名中获取变量的内容:
%suppose that I have structures variables in the workspace:
struct_1=struct('field1' ,"str",'field2',0:5)
struct_2=struct('field1' ,"str",'field2',0:10)
struct_3=struct('field1' ,"str",'field2
我有一个非常普通的ViewModel,我正在尝试将一个值的集合绑定到一个组合框。问题是没有什么是有约束力的。我已经检查了ViewModel构造函数,数据正在被加载,所以我怀疑它在我的XAML中,但我就是找不到它在哪里。
public class OwnerOccupierAccountViewModel : ViewModelBase
{
readonly UserAccountContext _userAccountContext;
readonly LoadOperation<Structure> _loadStructures;

我是多线程世界的新手,我只想编写一个比较(大型)排序的2D数组的函数:
function check_duplicates(sites, generated_structures)
for i in eachindex(generated_structures)
sites == generated_structures[i] && return false
end
return true
end
"generated_structures“可能很大(5M+元素),为了加快速度,我想做这样的事情:
function check_d
package data_structures;
import java.util.StringTokenizer;
public class ExpressionEvaluator implements Stack, Queue {
private String userInput;
public ExpressionEvaluator() {
Userinput = null;
}
Iterator<E> st = new StringTokenizer();
token = st.next();

所以我有几个.txt文件,每行超过500.000行。在所有这些文件中,我都有一个部分,我想将其提取到自己的.txt文件中。
为此,我使用以下代码:
for i, structure in enumerate(structures):
with open("data.txt", 'r') as f:
structure_data = open('data_new.txt'), 'w')
copy = False
for line in f:
