Rotating a matrix

Module: matrices()
Method : rotateImage(matrix,n,hint=False)
Uses : To rotate an input square matrix, this function retruns nothing but changes the input square matrix itself.
Parameters : matrix - a two dimensional array as python list, n is the number of rows in the matrix, hint is passed False by default, by declaring hint=True a detailed description of the rotation algorithm can be found.

                              Python Code Example
                              from edualgo import algorithms as al
img_arr = [[1,2,3],[4,5,6],[7,8,9]]
ping2 = al.matrices()
ping2.rotateImage(img_arr,3)
                              Output:
img_arr = [[7, 4, 1], [8, 5, 2], [9, 6, 3]]

    
    For getting the hint just pass hint=True in the function like - rotateImage(img_arr,n,True).
                            

Set Zeros

Module: matrices()
Method : setZeros(matrix,row,column)
Uses : This function sets the entire row and column of the matrix as zero if it encounters zero at any position of the matrix. This function returns nothing, the changes take place in the input matrix itself.
Parameters : matrix - a two dimensional array as python list, row - the number of rows in the matrix,columns - the number of columns in the matrix.

                              Python Code Example
                              from edualgo import algorithms as al
img_arr = [[1,0,3],[4,5,6],[7,8,9]]
ping2 = al.matrices()
ping2.setZeros(img_arr,3,3)
                              Output:
img_arr = [[0, 0, 0], [4, 0, 6], [7, 0, 9]]
