Leet Code Rotate Image

Leet Code Rotate Image 

You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise).

Example 1:

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

Example 2:

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

 

Constraints:

• n == matrix.length == matrix[i].length
• 1 <= n <= 20
• -1000 <= matrix[i][j] <= 1000

class Solution:

    def rotate(self, matrix):

        order = len(matrix[0])

        newmatrix = []

        for i in range(order):

            newmatrix.append([])

            for j in range(order):

                newmatrix[i].append(0)

        newColoumn = []

        for i in range(order):

            newColoumn.append(order-1-i)

        for i in range(order):

            for j in range(order):

                newmatrix[j][newColoumn[i]] = matrix[i][j]

        for i in range(order):

            for j in range(order):

                matrix[i][j] = int(newmatrix[i][j])

        print(matrix)

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

obj.rotate(matrix)
