recursive calculations..

[player123]

hi there! i cant figure out how i could program a little function in assembly using the PCSPIM environment.
the function i want to program with recursion is:

func = func(n-1) + (n-1)

this is similiar to the fibonnaci function which is:

fib = fib(n-1) + fib(n-2)

and the code for the fibonnaci can be found here:

https://www.cs.tcd.ie/John.Waldron/itral/source/fibloop.a

how can i change in order to make it work with:

func = func(n-1) + (n-1)

i tried plenty of times but i find it hard! all help will be greately appreciated!
thanks!

Post one of your better attempts at solving the problem.

The only real trick is making sure that you have an exit condition which stops further recursion.
