Task $1$: Write a program that asks the user to enter a positive integer N$.$ The program then

computes and prints the sum of all numbers between $1$ and N $($inclusive$).$

a$)$ Do this using standard $($iterative$)$ technique $($a for loop and an accumulator variable$)$

b$)$ Now repeat the same task, but this time by defining a recursive function summe$($N$).$

Hint: The factorial example above should be a good starting point.

c$)$ Try both solutions for a large number, say N$=500$
