question:What methods do the writers use to introduce or develop William as a key individual? Provide evidence (e.g., allusion, anecdotes, description, dialogue, examples, inner thoughts). answer these questions about willam from the boy who harnessed the wind from chapter 1

answer:In Chapter 1 of "The Boy Who Harnessed the Wind," the writers use several methods to introduce and develop William as a key individual: 1. Description: The writers provide physical descriptions of William, stating that he is a "skinny boy with a high forehead" (Chapter 1). This description helps readers visualize him as the story unfolds. 2. Anecdotes: The writers share anecdotes from William's childhood that highlight his curiosity and determination. They mention how William loved to dismantle broken radios and other appliances to learn how they worked. This anecdote showcases his natural inclination for understanding technology and hints at his future achievements. 3. Dialogue: Through conversations with his friends and family, the writers reveal William's unique perspective and ambitions. For example, William expresses his interest in building a windmill to generate electricity for his village. His dialogue showcases his innovative thinking and drive to bring positive change to his community. 4. Inner Thoughts: The writers provide insights into William's inner thoughts to highlight his dreams and aspirations. They mention his desire to "bring light into his family's life," and how he believes that "someday his life would change." These inner thoughts show his determination to improve the lives of those around him. 5. Example: The writers provide an example of William's resourcefulness when he uses his knowledge of scavenging to find scrap metal and bicycle parts to build a prototype windmill. This example demonstrates his ability to think outside the box and make the most of the limited resources available to him. By employing these methods, the writers effectively introduce and develop William as a key individual in the first chapter. They portray him as a curious, determined, and innovative young boy with a strong desire to improve the quality of life for his family and community.

question:hãy giải thích code này : #include <bits/stdc++.h> using namespace std; using ll=long long; int main() { int ans=0,sum=0; int n; cin>>n; int a[n]; for(auto &x : a)cin>>x; for(int i=0; i<n; i++) { sum+=a[i]; } sort(a,a+n); if(n%3==0) { for(int i=0; i<n; i++) { if(i%3==0) { ans+=a[i]; } } cout<<sum-ans; } else if(n%3==1) { for(int i=1; i<n; i++) { if((i-1)%3==0) { ans+=a[i]; } } cout<<sum-ans; } else if(n%3==2) { for(int i=0; i<n; i++) { if((i-2)%3==0) { ans+=a[i]; } } cout<<sum-ans; } return 0; }

answer:Code này có chức năng tính tổng của một mảng số nguyên và sau đó trừ đi tổng của các phần tử ở vị trí chia hết cho 3 trong mảng đã sắp xếp. - Dòng 1: `#include <bits/stdc++.h>` là một câu lệnh tiền xử lý dùng để gọi toàn bộ các thư viện chuẩn của C++ (có sẵn trong thư viện `bits/stdc++.h`). - Dòng 3: `using namespace std;` dùng để trỏ tới không gian tên (namespace) `std`, giúp việc sử dụng các thành phần (hàm, lớp, biến) của thư viện chuẩn trở nên thuận tiện hơn. - Dòng 4: `using ll=long long;` tạo một định danh `ll` cho kiểu dữ liệu `long long` để thuận tiện cho việc sử dụng. - Dòng 6-25: Định nghĩa hàm `main` chứa logic chính của chương trình. - Dòng 8-9: Khai báo và khởi tạo biến `ans` và `sum` có giá trị ban đầu bằng 0. - Dòng 11: Khai báo biến `n` để lưu số phần tử của mảng và đọc giá trị từ người dùng. - Dòng 12: Khai báo mảng `a` chứa `n` phần tử. - Dòng 13: Sử dụng vòng lặp `for-each` để đọc giá trị của mỗi phần tử trong mảng từ người dùng. - Dòng 14-16: Tính tổng các phần tử trong mảng `a` và lưu vào biến `sum`. - Dòng 17: Sắp xếp các phần tử trong mảng `a` theo thứ tự tăng dần. - Dòng 18-33: Kiểm tra số phần tử của mảng `a` chia hết cho 3 hay không để tính `ans` và in kết quả tương ứng. - Dòng 35: Trả về giá trị 0 để kết thúc chương trình.

question:sort(a,a+n); dòng này để làm gì

answer:Dòng `sort(a, a+n)` trong code được sử dụng để sắp xếp các phần tử trong mảng `a` theo thứ tự tăng dần. Hàm `sort()` trong thư viện `<algorithm>` được sử dụng để sắp xếp các phần tử trong một dải (range) từ `a` đến `a+n-1`. Dải này được định nghĩa bởi hai con trỏ (pointer) `a` và `a+n`. Qua việc sắp xếp lại các phần tử, mảng `a` được thay đổi để có thứ tự tăng dần.
