Hướng dẫn python max heap for string - đống tối đa python cho chuỗi

Question

Bạn có thể xây dựng một MaxHeap từ các chuỗi của mình bằng cách sử dụng heapq để xây dựng một chiếc Minheap của các đối tượng giống như chuỗi có nội dung ký tự giống như các chuỗi ban đầu của bạn nhưng có các toán tử so sánh (và do đó thứ tự sắp xếp của chúng) tạo ra kết quả đối nghịch với bình thường Đối tượng chuỗi. Nếu chúng ta gọi đối tượng đó là contra_string thì nó sẽ được xác định như thế này:

Nội dung chính Show

Có một đống tối đa trong Python?
Python Heapq có phải là một đống tối đa hay tối đa không?
Làm thế nào để bạn viết Max Heap trong Python?
Tại sao không có đống tối đa trong Python?

class contra_string(str):

    def __init__(self, s):
       self.original = s

    def __lt__(self, s):
        return self.original.__gt__(s)

    def __le__(self, s):
        return self.original.__ge__(s)

    def __eq__(self, s):
        return self.original.__eq__(s)

    def __ne__(self, s):
        return self.original.__ne__(s)

    def __gt__(self, s):
        return self.original.__lt__(s)

    def __ge__(self, s):
        return self.original.__le__(s)

    def normal(self):
        return self.original

Nó sẽ được sử dụng như thế này:

import heapq

mystrings = [ 'b', 'c', 'a', 'bravo', 'alpha', 'charlie' ]

maxheap = [contra_string(s) for s in mystrings]
heapq.heapify(maxheap)

print [heapq.heappop(maxheap) for n in range(len(maxheap))]
# prints "['charlie', 'c', 'bravo', 'b', 'alpha', 'a']"

Hãy nhớ rằng các đối tượng trong đống là trường hợp của contra_string, vì vậy chúng sẽ cư xử kỳ lạ nếu bạn sử dụng chúng trong so sánh sau khi bạn bật chúng ra khỏi đống. Nếu bạn cần phải làm bất cứ điều gì liên quan đến các so sánh chuỗi được đặt hàng tự nhiên với các đối tượng đó sau khi trích xuất chúng thì bạn có thể khôi phục chuỗi thông thường ban đầu bằng cách sử dụng phương thức normal trên contra_string và tất nhiên so sánh bằng cách sử dụng các chuỗi ban đầu đó sẽ hoạt động bình thường. Điều đó sẽ giống như:

original_strings_in_reverse_order = [heapq.heappop(maxheap).normal() for n in range(len(maxheap))]
print type(original_strings_in_reverse_order[0])
# prints ""

Có một đống tối đa trong Python?

Max-heap là một cây nhị phân hoàn chỉnh trong đó giá trị trong mỗi nút bên trong lớn hơn hoặc bằng các giá trị ở trẻ em của nút đó..

Python Heapq có phải là một đống tối đa hay tối đa không?

Mô -đun HEAPQ của Python thực hiện thuật toán hàng đợi Heap.Nó sử dụng các đống tối thiểu trong đó chìa khóa của cha mẹ nhỏ hơn hoặc bằng với con của nó.min heap where the key of the parent is less than or equal to those of its children.

Làm thế nào để bạn viết Max Heap trong Python?

Một đống trong Python là theo mặc định Min-heap và được sử dụng bằng các hàm Heapf, Heppop và Heppush của mô-đun Heapq.Để tạo và sử dụng tối đa bằng cách sử dụng các chức năng thư viện, chúng ta có thể nhân mỗi phần tử với -1 và sau đó sử dụng hàm thư viện Heap và do đó nó sẽ hoạt động như một phần lớn.multiply each element with -1 and then use the heap library function, and hence it will act as a max-heap.

Tại sao không có đống tối đa trong Python?

Những người có trường hợp sử dụng thực tế chưa được yêu cầu hành vi (và một lần thường xuyên được nhận bằng cách phủ nhận đối số số).Đó là lý do tại sao các chức năng MaxHeap được cố tình làm riêng tư. (and the occasional one-off gets by negating the numeric argument). That is why the maxheap functions were intentionally made private.
