Possible recursion scenario?

[dbillings]

Does this make sense to anyone? Apparently the ... means that other statements are there they are just omitted, it's a head scratcher for me.

 

Assuming that n is an integer argument, write a function to compute f(n) where

f(n) = 1 + 2 + 3 + … + n

Then, write a function to compute g(n) where

g(n) = f(1) + f(2) + … f(n)

F of n = Increment by 1 starting at one until you reach n

G of n = Increment by f(1) starting at f(1) until you reach f(n).

 

seems pretty straight forward to me

[dbillings]

what do you mean f of n and g of n?

[Zane]

F of n is the same as f(n)

and f(n) is the same as say.....

 

myNewFunction($parameter)

 

technically you'd call that myNewFunction of $parameter

Thanks Zanus I appreciate the help. I get the concept.

<?php
function f_and_g($n){
while ($i <$n){
	$i++;
	$f += $i;
	$g += $f;
}
return array('f' => $f, 'g' => $g);
}
$r = f_and_g(3);
print_r($r);
?>
