Solution 1
The problem is asking to find the minimum number of moves to make the matrix beautiful. A matrix is beautiful if the single number one of the matrix is located in its middle. You are allowed to swap two neighboring matrix rows or two neighboring matrix columns.
Here are the steps to solve the problem:
-
First, find the position of the number one in the matrix. You can do this by iterating over the matrix. Let's say the position of the number one is (x, y).
-
The position of the middle of the matrix is always (3, 3) because it's a 5x5 matrix.
-
The minimum number of moves to make the matrix beautiful is the sum of the absolute differences between the x and y coordinates of the current position of the number one and the middle of the matrix. This is because you can move the number one to the middle by swapping it with its neighboring rows or columns.
-
So, the minimum number of moves is |x - 3| + |y - 3|.
For example, if the input is:
0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
The position of the number one is (2, 5). So, the minimum number of moves is |2 - 3| + |5 - 3| = 1 + 2 = 3.
If the input is:
0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0
The position of the number one is (3, 2). So, the minimum number of moves is |3 - 3| + |2 - 3| = 0 + 1 = 1.
Solution 2
The problem is asking to find the minimum number of moves to get the number one to the center

Ben is studying matrices and wants to write a program that swaps two rows of a matrix (N, M), the program takes an input matrix, swaps the specified rows, and then displays the modified matrix.Assist him with the program.Input format :The first line consists of two space-separated integers N and M, representing the number of rows and columns in the matrix.The next N lines contain M space-separated integers each, representing the elements of the matrix.The last line consists of two space-separated integers r1 and r2, representing the row numbers to be interchanged.Output format :If the input row numbers r1 or r2 are invalid (less than 1 or greater than the number of rows), the output prints "Invalid row numbers".Otherwise, the modified matrix is printed after swapping the specified rows.
7.25 LAB: Flip MatrixWrite a function that flips the values of an n x n matrix along its diagonal. The diagonal is defined as the elements with the same index on both axes (i.e., 0,0 or 1,1 and so on). Elements that lie on the diagonal are not changed while other elements are swapped with the opposite position (i.e., element in [1][3] switched with [3][1]). Ensure that a valid matrix is provided.Ex: If the input is:16 3 2 135 10 11 89 6 7 124 15 14 1the output is:16 5 9 4 3 10 6 15 2 11 7 14 13 8 12 1 Hint: Use nested loops to iterate through the matrix and swap the appropriate elements.
