Tìm kiếm và sắp xếp Python: Bài tập-1 với giải pháp
Viết một chương trình Python cho tìm kiếm nhị phân. Tìm kiếm nhị phân: Trong khoa học máy tính, một tìm kiếm nhị phân hoặc thuật toán tìm kiếm nửa giữa các lần tìm thấy vị trí của giá trị đích trong một mảng được sắp xếp. Thuật toán tìm kiếm nhị phân có thể được phân loại là thuật toán tìm kiếm phân chia và chinh phục phân chia và thực thi trong thời gian logarit.
Binary Search : In computer science, a binary search or half-interval search algorithm finds the position of a target value within a sorted array. The binary search algorithm can be classified as a
dichotomies divide-and-conquer search algorithm and executes in logarithmic time.
Ví dụ từng bước:
Giải pháp mẫu::
Mã Python:
def binary_search[item_list,item]:
first = 0
last = len[item_list]-1
found = False
while[ first>> x = [1, 2, 3, 4]
>>> k = 2
>>> x[-2:] + x[:-2]
[3, 4, 1, 2]
Tôi tương đối mới với Python [3.3] và tôi chỉ đang cố gắng thực hiện tìm kiếm nhị phân thông qua danh sách các từ và không thể tìm ra cách khắc phục các loại toán hạng của mình khi nói đến việc lặp lại các chỉ số ... tôi Tiếp tục có được kiểu mẫu. Không thể tìm ra bất kỳ cách nào xung quanh nó
Nội phân chính
- Tôi có thể sử dụng tìm kiếm nhị phân trên chuỗi không?
- Làm thế nào để bạn viết một tìm kiếm nhị phân trong Python?
- Có tìm kiếm nhị phân trong Python không?
- Tìm kiếm nhị phân trong Python với ví dụ là gì?
def find[L, target]:
start = 0
end = len[L] - 1
while start target:
end = midpoint - 1
elif midpoint < target:
start = midpoint + 1
else:
return midpoint
Tìm kiếm nhị phân là một thuật toán tìm kiếm được sử dụng để tìm kiếm một phần tử từ một mảng được sắp xếp. Nó không thể được sử dụng để tìm kiếm từ một mảng chưa được phân loại. Tìm kiếm nhị phân là một thuật toán hiệu quả và tốt hơn so với tìm kiếm tuyến tính về độ phức tạp về thời gian. Độ phức tạp thời gian của tìm kiếm tuyến tính là O [N].

Tdelaneyinput and the bug with incrementing and decrementing midpoint instead of middle.

Logic của bạn có vẻ tốt, ngoại trừ đầu vào và lỗi với điểm giữa tăng và giảm thay vì giữa.Dec 17, 2015 at 5:40

Như người khác chỉ ra, hãy sử dụng giữa thay vì điểm giữa3 gold badges36 silver badges51 bronze badges
Và để sử dụng tối ưu tìm kiếm nhị phân, hãy sắp xếp danh sách trướcDec 17, 2015 at 5:44

Tôi có thể sử dụng tìm kiếm nhị phân trên chuỗi không?
Tìm kiếm nhị phân đang tìm kiếm kỹ thuật hoạt động bằng cách tìm phần giữa của mảng để tìm phần tử. Đối với mảng chuỗi, thuật toán tìm kiếm nhị phân sẽ vẫn giữ nguyên. Nhưng các so sánh được thực hiện sẽ dựa trên so sánh chuỗi.For array of strings also the binary search algorithm will remain the same. But the comparisons that are made will be based on string comparison.
Làm thế nào để bạn viết một tìm kiếm nhị phân trong Python?

Có tìm kiếm nhị phân trong Python không?
Một tìm kiếm nhị phân Python là một thuật toán tìm thấy vị trí của một phần tử trong một mảng được đặt hàng. Tìm kiếm nhị phân liên tục chia một danh sách thành hai nửa. Sau đó, một tìm kiếm so sánh nếu một giá trị cao hơn hoặc thấp hơn giá trị trung bình trong danh sách.. Binary searches repeatedly divide a list into two halves. Then, a search compares if a value is higher or lower than the middle value in the list.
Tìm kiếm nhị phân trong Python với ví dụ là gì?
Tìm kiếm nhị phân là một thuật toán tìm kiếm được sử dụng để tìm kiếm một phần tử từ một mảng được sắp xếp. Nó không thể được sử dụng để tìm kiếm từ một mảng chưa được phân loại. Tìm kiếm nhị phân là một thuật toán hiệu quả và tốt hơn so với tìm kiếm tuyến tính về độ phức tạp về thời gian. Độ phức tạp thời gian của tìm kiếm tuyến tính là O [N].a searching algorithm which is used to search an element from a sorted array. It cannot be used to search from an unsorted array. Binary search is an efficient algorithm and is better than linear search in terms of time complexity. The time complexity of linear search is O[n].
