Hướng dẫn counter max python - truy cập trăn tối đa

Đưa ra một loạt các số nguyên có độ dài n, chương trình phải tìm giá trị lặp lại với số lần tối đa và in số. Trong trường hợp cà vạt, chọn số nhỏ hơn và in nó.

Nội dung chính ShowShow

  • Làm thế nào để bạn in một số lặp lại tối đa trong Python?
  • Hàm nào trả về giá trị lặp lại tối đa?
  • Làm thế nào để bạn tìm thấy phần tử lặp lại tối đa trong một mảng?
  • Làm thế nào để bạn tìm thấy phần tử lặp lại tối đa trong một mảng trong Java?

Điều kiện biên: Độ dài của mảng N sẽ từ 2 đến 100Length of array N will be from 2 to 100
Length of array N will be from 2 to 100

Định dạng đầu vào: Dòng đầu tiên sẽ chứa mảng các số nguyên có độ dài n được phân tách bằng một hoặc nhiều khoảng trắng.First line will contain the array of integers of length N separated by one or more spaces.
First line will contain the array of integers of length N separated by one or more spaces.

Định dạng đầu ra: Giá trị số nguyên lặp lại số lần tối đa.The integer value which repeats the maximum number of times.
The integer value which repeats the maximum number of times.

Mẫu đầu vào/đầu ra: Ví dụ 1: Đầu vào: 10 20 30 20 30 10 30 20 Nhưng 20 là số nhỏ hơn và do đó 20 được in dưới dạng đầu ra. Ví dụ 2:Example 1:Input:10 20 30 20 30 10 30 20Output:20Explanation:Both 20 and 30 repeats three times. But 20 is the smaller number and hence 20 is printed as output. Example 2:
Example 1:
Input:
10 20 30 20 30 10 30 20
Output:
20
Explanation:
Both 20 and 30 repeats three times. But 20 is the smaller number and hence 20 is printed as output. Example 2:

Đầu vào: 1 2 3 5 9 2 9 6 9Output: 9 Explanation: 9 Lặp lại ba lần nhiều hơn số lượng lặp lại của bất kỳ số nào khác.1 2 3 5 9 2 9 6 9Output:9Explanation:9 repeats thrice which is more than the repetition count of any other number.
1 2 3 5 9 2 9 6 9
Output:
9
Explanation:
9 repeats thrice which is more than the repetition count of any other number.

n=[int(i) for i in input().split()]
print(max(n,key=n.count))

Đầu ranaive approach is to run two loops, the outer loop picks an element one by one, and the inner loop counts a number of occurrences of the picked element. Finally, return the element with a maximum count. The time complexity of this approach is O(n^2).A better approach is to create a count array of size k and initialize all elements of count[] as 0. Iterate through all elements of input array, and for every element arr[i], increment count[arr[i]]. Finally, iterate through count[] and return the index with maximum value. This approach takes O(n) time, but requires O(k) space.naive approach is to run two loops, the outer loop picks an element one by one, and the inner loop counts a number of occurrences of the picked element.

Finally, iterate through count[] and return the index with maximum value. This approach takes O(n) time, but requires O(k) space.

Sau đây là thời gian O (n) và O (1) Phương pháp tiếp cận không gian bổ sung. & Nbsp; Hãy cho chúng tôi hiểu cách tiếp cận với một ví dụ đơn giản trong đó ARR [] = {2, 3, 3, 5, 3, 4, 1, 7} , k = 8, n = 8 (số phần tử trong mảng []).O(n) time and O(1) extra space approach. Let us understand the approach with a simple example where arr[] = {2, 3, 3, 5, 3, 4, 1, 7}, k = 8, n = 8 (number of elements in arr[]).O(n) time and O(1) extra space approach. 
Let us understand the approach with a simple example where arr[] = {2, 3, 3, 5, 3, 4, 1, 7}, k = 8, n = 8 (number of elements in arr[]).

  1. Lặp mặc dù mảng đầu vào ARR [], cho mọi phần tử ARR [i], tăng arr [mảng [i]%k] bởi k (mảng [] trở thành {2, 11, 11, 29, 11, 12, 1, 15} )
  2. Tìm giá trị tối đa trong mảng đã sửa đổi (giá trị tối đa là 29). Chỉ số của giá trị tối đa là phần tử lặp lại tối đa (chỉ mục 29 là 3).
  3. Nếu chúng tôi muốn lấy lại mảng gốc, chúng tôi có thể lặp lại qua mảng một lần nữa và làm ARR [i] = mảng [i] % k trong đó tôi thay đổi từ 0 đến N-1.

Thuật toán trên hoạt động như thế nào? Vì chúng tôi sử dụng ARR [i]%K làm chỉ mục và thêm giá trị k tại chỉ số ARR [i]%k, chỉ số bằng phần tử lặp lại tối đa sẽ có giá trị tối đa cuối cùng. Lưu ý rằng K được thêm số lần tối đa tại chỉ số bằng phần tử lặp lại tối đa và tất cả các phần tử mảng nhỏ hơn K.following là triển khai C ++ của thuật toán trên. & NBSP;Following is C++ implementation of the above algorithm.

The above solution prints only one repeating element and doesn’t work if we want to print all maximum repeating elements. For example, if the input array is {2, 3, 2, 3}, the above solution will print only 3. What if we need to print both of 2 and 3 as both of them occur maximum number of times. Write a O(n) time and O(1) extra space function that prints all maximum repeating elements. (Hint: We can use maximum quotient arr[i]/n instead of maximum value in step 2).
Note that the above solutions may cause overflow if adding k repeatedly makes the value more than INT_MAX.  


Làm thế nào để bạn in một số lặp lại tối đa trong Python?

Khoa học dữ liệu thực tế sử dụng Python...

N: = Kích thước của A ..

Đối với tôi trong phạm vi 0 đến n, làm. A [a [i] mod k]: = a [a [i] mod k] + k ..

MAX_VAL: = A [0].

Kết quả: = 0 ..

Đối với tôi trong phạm vi 1 đến n, làm. Nếu một [i]> max_val, thì. MAX_VAL: = A [i] Kết quả: = I ..

Kết quả trở lại ..

Hàm nào trả về giá trị lặp lại tối đa?

C ++ sử dụng STD không gian tên; // Trả về phần tử lặp lại tối đa trong ARR [0..N-1].arr[0..n-1].arr[0..n-1].

Làm thế nào để bạn tìm thấy phần tử lặp lại tối đa trong một mảng?
