Sum of numbers #WSQ07

I did the sum of numbers WSQ in here, first you need to learn how to use a loop, in my case I used while, after that you have to declare 2 variables, one for the sum and one for the counter, what I did is to ad +1 to the counter variable each time that the loop repeats and adding that variable to the variable sum.
