Write a program that takes as input five numbers and outputs the mean (average) and standard deviation of the numbers. If the numbers are x₁, x₂, x₃, x₄, and x₅, then the mean is x = (x₁ + x₂ + x₃ + x₄ + x₅)/5 and the standard deviation is:

Your program must contain at least the following functions: a function that calculates and returns the mean and a function that calculates the standard deviation.
