Answer to Question #262020 in Python for prime

Question

For this program, I want an exact output with all test cases passed and it should not have any brackets.

def rotate1(matrix, n):

 a = len(matrix)

 n = int(a)

 b = int(n/2)

 

 for row in range(0, b):

 for col in range(row, (n- row - 1)):

  temp = matrix[row][col]

  matrix[row][col] = matrix[n - 1 - col][row] 

  matrix[n - 1 - col][row] = matrix[n - 1 - row][n- 1 - col] 

  matrix[n - 1 - row][n - 1 - col] = matrix[col][n - 1 - row] 

  matrix[col][n - 1 - row] = temp 

 return matrix

matrix = [[1, 2, 3, 4],[5, 6, 7, 8],[9, 10, 11, 12],[13, 14, 15, 16]]

n = len(matrix)

array = rotate1(matrix, n)

for col in array:

 print(col, sep=" ")

Answer 1

def rotate1(matrix, n):


    a = len(matrix)
    
    n = int(a)
    
    b = int(n/2)


    for row in range(0, b):
    
        for col in range(row, (n- row - 1)):
    
            temp = matrix[row][col]
            
            matrix[row][col] = matrix[n - 1 - col][row] 
            
            matrix[n - 1 - col][row] = matrix[n - 1 - row][n- 1 - col] 
            
            matrix[n - 1 - row][n - 1 - col] = matrix[col][n - 1 - row] 
            
            matrix[col][n - 1 - row] = temp 


    return matrix






matrix = [[1, 2, 3, 4],[5, 6, 7, 8],[9, 10, 11, 12],[13, 14, 15, 16]]


n = len(matrix)


array = rotate1(matrix, n)


for i in range(4):
    for j in range(4):
        print(array[i][j],end=" ")
    print()
