        for i in range(rowStart, row):

            print(arr[i][columnStart], end =" ")

            

        columnStart = columnStart + 1

        

        for i in range (columnStart, column):

            print(arr[row-1][i], end=' ')

        row = row- 1

        if (rowStart < row):

            for i in range(row-1, rowStart-1, -1):
