Question

ПОМОГИТЕ!!!! 1)Дана матрица A(N,M). Поменять местами ее T и K элементы 2)Отсортировать четные строки массива по возрастанию, а нечетные по убыванию

Answer 1

Поменять местами элементы T и K в матрице A(N, M)

To swap the elements T and K in a matrix A(N, M), you can follow these steps:

1. Identify the positions of the elements T and K in the matrix. 2. Store the values of T and K in temporary variables. 3. Assign the value of K to the position of T and the value of T to the position of K.

Here's an example of how you can implement this in Python:

def swap_elements(matrix, T, K):
    # Find the positions of T and K in the matrix
    T_row, T_col = None, None
    K_row, K_col = None, None
    for i in range(len(matrix)):
        for j in range(len(matrix[i])):
            if matrix[i][j] == T:
                T_row, T_col = i, j
            elif matrix[i][j] == K:
                K_row, K_col = i, j
    
    # Swap the elements T and K
    matrix[T_row][T_col], matrix[K_row][K_col] = K, T
    
    return matrix

You can call this function with your matrix and the values of T and K to swap them. For example:

matrix = [[1, 2, 3],
          [4, 5, 6],
          [7, 8, 9]]

T = 2
K = 7

result = swap_elements(matrix, T, K)
print(result)

Output: ``` [[1, 7, 3], [4, 5, 6], [2, 8, 9]] ```

This code will swap the positions of the elements 2 and 7 in the matrix.

Please note that the code provided is just an example implementation in Python. You can adapt it to your specific programming language or requirements.
