Array: Statistics- Compute deviation

    Q: Write a program that takes 10 elements as input for a double array and calculates the mean and 
       standard deviation of the elements. 
       Mean= (n1+n2+n3+...+nl)/l
       Standard deviation= sqrt((summation(xi-mean)^2)/l)
       
       l= total number of elements
