programming python

Hướng dẫn how do you reverse a priority queue in python? - làm cách nào để đảo ngược hàng đợi ưu tiên trong python?

Mẫu phổ biến là chèn dữ liệu, như một tuple, cùng với mức độ ưu tiên. Vì vậy, bạn chỉ có thể thay đổi put như thế này

q.put[[-n ,n]]

Vì vậy, khi các bộ dữ liệu được so sánh, nếu các số là 9, 1, 4 và 5, chúng sẽ được so sánh như thế này [-9, 9], [-1, 1], [-4, 4] và [-5 , 5]. Vì, -9 là nhỏ nhất trong tất cả, nó sẽ được lấy đầu tiên và sau đó -5 và sau đó -4 và sau đó -1.

Example:

from Queue import PriorityQueue
numbers, Q = [9, 1, 4, 5], PriorityQueue[]
for number in numbers:
    Q.put[[-number, number]]

while not Q.empty[]:
    print Q.get[]

Đầu ra

[-9, 9]
[-5, 5]
[-4, 4]
[-1, 1]

Để chỉ nhận được giá trị thực tế, chỉ cần chỉ in phần tử thứ hai, như thế này

while not Q.empty[]:
    print Q.get[][1]

Đưa ra một thuật toán để đảo ngược hàng đợi Q. Chỉ được phép các hoạt động tiêu chuẩn sau đây được cho phép xếp hàng. & NBSP;Q. Only the following standard operations are allowed on queue. 

  1. Enqueue [x]: Thêm một mục X vào phía sau hàng đợi.: Add an item x to the rear of the queue.
  2. Dequeue []: Loại bỏ một mục từ phía trước hàng đợi.: Remove an item from the front of the queue.
  3. trống []: Kiểm tra xem hàng đợi có trống hay không.: Checks if a queue is empty or not.

Nhiệm vụ là đảo ngược hàng đợi.

Examples:  

Đầu vào: Q = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100] Đầu ra: Q = [100, 90, 80, 70, 60, 50, 40, 30, 20, 10]Q = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
Output: Q = [100, 90, 80, 70, 60, 50, 40, 30, 20, 10]

Đầu vào: [1, 2, 3, 4, 5] Đầu ra: [5, 4, 3, 2, 1][1, 2, 3, 4, 5]
Output: [5, 4, 3, 2, 1]

Đảo ngược một hàng đợi bằng ngăn xếp:

Để đảo ngược, một cách tiếp cận, một cách tiếp cận có thể là lưu trữ các yếu tố của hàng đợi trong cấu trúc dữ liệu tạm thời theo cách mà nếu chúng ta kiểm tra lại các phần tử trong hàng đợi, chúng sẽ được chèn theo thứ tự ngược lại. Vì vậy, bây giờ nhiệm vụ của chúng tôi là chọn một cấu trúc dữ liệu như vậy có thể phục vụ mục đích. Theo cách tiếp cận, cấu trúc dữ liệu phải có thuộc tính của ‘LIFO, là phần tử cuối cùng được chèn vào cấu trúc dữ liệu thực sự là phần tử đầu tiên của hàng đợi đảo ngược. & NBSP;

Thực hiện theo các bước dưới đây để thực hiện ý tưởng:

  • Pop các phần tử từ hàng đợi và chèn vào ngăn xếp bây giờ phần tử cao nhất của ngăn xếp là yếu tố cuối cùng của hàng đợi.
  • Pop các phần tử của ngăn xếp để chèn lại vào hàng đợi phần tử cuối cùng là phần đầu tiên được chèn vào hàng đợi.

Dưới đây là việc thực hiện phương pháp trên:

Đầu ra

Độ phức tạp về thời gian: O [n], vì chúng ta cần chèn tất cả các phần tử trong ngăn xếp và sau đó vào hàng đợi.AUXILIARY: O [n], sử dụng ngăn xếp để lưu trữ các giá trị. & NBSP;

  • Đảo ngược một hàng đợi bằng cách sử dụng đệ quy: & nbsp;
    • Thay vì sử dụng rõ ràng mục tiêu ngăn xếp có thể đạt được bằng cách sử dụng đệ quy [đệ quy ở phần phụ sẽ tự duy trì ngăn xếp].0 return.
    • Thực hiện theo các bước dưới đây để thực hiện ý tưởng:
    • Thực hiện đệ quy các bước sau:

Có hàng đợi ưu tiên trong Python không?

Hàng đợi ưu tiên là các cấu trúc dữ liệu trừu tượng trong đó mỗi dữ liệu/giá trị trong hàng đợi có mức độ ưu tiên nhất định.Ví dụ, trong các hãng hàng không, hành lý với tiêu đề kinh doanh, hoặc hạng nhất của nhóm đến sớm hơn phần còn lại.Hàng đợi ưu tiên là một phần mở rộng của hàng đợi với các thuộc tính sau.

Hàng đợi ưu tiên có tự động sắp xếp Python không?

Một hàng đợi ưu tiên không được cho là sắp xếp.Hàng đợi ưu tiên chỉ đảm bảo rằng khi bạn gọi get [], nó sẽ trả lại cho bạn mục ưu tiên cao nhất.. The priority queue only guarantees that when you call get[] , it returns you the highest priority item.

Là hàng đợi ưu tiên Python an toàn?

Ưu tiên trong Python 3].Nó hoàn toàn an toàn.It is fully thread-safe.

Bạn có thể tìm kiếm một hàng đợi ưu tiên?

Hàng đợi tìm kiếm ưu tiên là sự pha trộn tuyệt vời của các bản đồ hữu hạn [hoặc từ điển] và hàng đợi ưu tiên, nghĩa là chúng hỗ trợ cả hai hoạt động từ điển [ví dụ: truy cập vào một liên kết với một khóa đã cho] và các hoạt động hàng đợi trước đó [ví dụ: truy cậpliên kết với giá trị tối thiểu]., that is, they support both dictionary operations [for instance, accessing a binding with a given key] and prior- ity queue operations [for instance, accessing a binding with the minimum value].
