AVIRAL_AKASH ==> Mean-variance-standard-deviation-calculator

Mean-Variance-Standard Deviation Calculator:-
Create a function named calculate() in mean_var_std.py that uses Numpy to output the mean,
variance, standard deviation, max, min, and sum of the rows, columns, and elements in a 3 x 3 matrix.

The input of the function should be a list containing 9 digits. The function should convert the list into a 3 x 3 Numpy array,
and then return a dictionary containing the mean, variance, standard deviation, max, min, and sum along both axes and for the flattened matrix.
