$begingroup$
for i = 1 to n do
for j = i to n^2 do
print (i, j).
So here is what I've got
$sum_i=1^n sum_j=i^n^2 $
$Csum_i=1^n sum_j=i^n^2 1 $
$Csum_i=1^n (n^2-i+1) $
$Csum_i=1^n n^2 - sum_i=1^n i + sum_i=1^n 1 $
Which becomes
$n^3 + dfracn(n+1)2 + n$
And since the term with the highest exponent dominates
$O( n^3)$
Now I'm a complete beginner, and I came up with this solution by going over my notes.
Was this the correct solution? If not how would I solve this problem?

That's exactly how I would do it.
Looks fine to me.

Alright what had me really psyched was $Csum_i=1^n (n^2-i+1)$ because I'm not really sure of the logic behind that step and kind of just adapted it from notes
