Diện tích hình vuông
Đưa ra một ma trận MXN chứa đầy
Dòng đầu vào đầu tiên sẽ chứa hai số nguyên được phân tách không gian, biểu thị M và N.
Các dòng M tiếp theo sẽ chứa các số nguyên được phân tách không gian, biểu thị các phần tử của ma trận.
Đầu ra phải là một dòng duy nhất chứa diện tích của hình vuông tối đa.
Ví dụ: nếu M, N và các yếu tố của ma trận đã cho là như sau
4 5
X o x o o
X o x x x
X X O X X
X o o x o
Ma trận từ các chỉ số [1, 3] đến [2, 4] có hình vuông tối đa với
X. Vì vậy, đầu ra phải là diện tích của hình chữ nhật tối đa với x, là 4.

Đưa ra một ma trận trong đó mọi yếu tố là ‘O, hoặc‘ X, hãy tìm phần phụ lớn nhất được bao quanh bởi ‘X, & NBSP; Trong bài viết dưới đây, người ta cho rằng ma trận đã cho cũng là một ma trận vuông. Mã được đưa ra dưới đây có thể dễ dàng mở rộng cho ma trận hình chữ nhật.
In the below article, it is assumed that the given matrix is also a square matrix. The code given below can be easily extended for rectangular matrices.
Examples:
Input: mat[N][N] = { {'X', 'O', 'X', 'X', 'X'},
{'X', 'X', 'X', 'X', 'X'},
{'X', 'X', 'O', 'X', 'O'},
{'X', 'X', 'X', 'X', 'X'},
{'X', 'X', 'X', 'O', 'O'},
};
Output: 3
The square submatrix starting at [1, 1] is the largest
submatrix surrounded by 'X'
Input: mat[M][N] = { {'X', 'O', 'X', 'X', 'X', 'X'},
{'X', 'O', 'X', 'X', 'O', 'X'},
{'X', 'X', 'X', 'O', 'O', 'X'},
{'X', 'X', 'X', 'X', 'X', 'X'},
{'X', 'X', 'X', 'O', 'X', 'O'},
};
Output: 4
The square submatrix starting at [0, 2] is the largest
submatrix surrounded by 'X'Một giải pháp đơn giản là xem xét mỗi Submatrix vuông và kiểm tra xem có phải tất cả các cạnh góc chứa đầy ‘X. Độ phức tạp thời gian của giải pháp này là O [N4]. Chúng tôi có thể giải quyết vấn đề này trong thời gian O [N3] bằng không gian thêm. Ý tưởng là tạo hai mảng phụ trợ hor [n] [n] và ver [n] [n]. Giá trị được lưu trữ trong hor [i] [j] là số lượng các ký tự ‘x liên tục cho đến khi mat [i] [j] trong mat [] []. Tương tự, giá trị được lưu trữ trong ver [i] [j] là số lượng các ký tự ‘x liên tục cho đến khi mat [i] [j] trong mat [] []. & Nbsp;Simple Solution is to consider every square submatrix and check whether is has all corner edges filled with ‘X’. The time complexity of this solution is
O[N4].
We can solve this problem in O[N3] time using extra space. The idea is to create two auxiliary arrays hor[N][N] and ver[N][N]. The value stored in hor[i][j] is the number of horizontal continuous ‘X’ characters till mat[i][j] in mat[][]. Similarly, the value stored in ver[i][j] is the number of vertical continuous ‘X’ characters till mat[i][j] in mat[][].
Example:
mat[6][6] = X O X X X X
X O X X O X
X X X O O X
O X X X X X
X X X O X O
O O X O O O
hor[6][6] = 1 0 1 2 3 4
1 0 1 2 0 1
1 2 3 0 0 1
0 1 2 3 4 5
1 2 3 0 1 0
0 0 1 0 0 0
ver[6][6] = 1 0 1 1 1 1
2 0 2 2 0 2
3 1 3 0 0 3
0 2 4 1 1 4
1 3 5 0 2 0
0 0 6 0 0 0Khi chúng ta đã điền các giá trị trong hor [] [] và ver [] [] [], chúng ta bắt đầu từ góc trên cùng của ma trận và di chuyển về phía cuối cùng bên trái theo từng hàng. Đối với mỗi thảm nhập được truy cập [i] [j], chúng tôi so sánh các giá trị của hor [i] [j] và ver [i] [j], và chọn nhỏ hơn hai khi chúng tôi cần một hình vuông. Hãy để hai người nhỏ hơn là ’nhỏ. Sau khi chọn nhỏ hơn hai, chúng tôi kiểm tra xem cả Ver [] [] và Hor [] [] [] cho các cạnh trái và lên tương ứng. Nếu họ có các mục cho cùng, thì chúng tôi đã tìm thấy một chương trình phụ. Nếu không, chúng tôi cố gắng cho Small-1. & NBSP;
Dưới đây là triển khai ý tưởng trên. & NBSP;

Phương pháp tối ưu hóa:
Một giải pháp được tối ưu hóa hơn sẽ là tính trước số lượng ’x, theo chiều ngang và chiều dọc, trong một ma trận của các cặp có tên DP. Bây giờ & nbsp; Đối với mỗi mục nhập của DP, chúng tôi có một cặp [int, int] biểu thị mức độ tiếp giáp tối đa ‘X, cho đến điểm đó, tức là.dp. Now for every entry of dp we have a pair [int, int] which denotes the maximum contiguous ‘X’ till that point, i.e.
- DP [i] [j]. Đầu tiên biểu thị sự tiếp giáp ’x, được thực hiện theo chiều ngang cho đến điểm đó.
- dp [i] [j] .second biểu thị sự tiếp giáp ’x, được thực hiện theo chiều dọc cho đến thời điểm đó.
Bây giờ, một hình vuông có thể được hình thành với dp [i] [j] là góc dưới bên phải, có các cạnh tối đa chiều dài, min [dp [i] [j] .first, dp [i] [j] .second]min[dp[i][j].first, dp[i][j].second]
Vì vậy, chúng tôi tạo ra một ma trận Maxside khác, sẽ biểu thị phía hình vuông tối đa hình thành có góc dưới bên phải là mảng [i] [j]. Chúng tôi sẽ cố gắng để có được một số trực giác từ các thuộc tính của một hình vuông, tức là tất cả các cạnh của hình vuông đều bằng nhau.maxside, which will denote the maximum square side formed having the bottom right corner as arr[i][j]. We’ll try to get some intuition from the properties of a square, i.e. all the sides of the square are equal.
Hãy để lưu trữ giá trị tối đa có thể thu được, như val = min [dp [i] [j] .first, dp [i] [j] .second]. Từ điểm [i, j], chúng tôi đi qua phía sau theo khoảng cách theo khoảng cách Val và kiểm tra xem liệu tiếp giáp thẳng đứng tối thiểu ‘X, cho đến khi điểm đó bằng với Val.
Tương tự, chúng tôi đi qua phía sau theo chiều dọc theo khoảng cách Val và kiểm tra xem liệu tiếp giáp ngang tối thiểu ‘X, cho đến khi điểm đó bằng Val? Ở đây chúng tôi đang sử dụng thực tế là tất cả các mặt của hình vuông đều bằng nhau.
