Im new to functional programming and I have an assignment to compute partial sum of a list. E.g. - psum [1,1,1,1,1]; val it = [1,2,3,4,5] : int list
Here is the my code so far. However in function psum2[L] i dont know how to go through each value and add them up so I just print the list.
fun psum2(L) : int list =
if L=nil then []
else L;
fun pSum(L) : int list =
psum2(L);
exception Empty_List;
psum([2,3,4]);
Your question is a little broad, but here's one way to sum a list. Perhaps you can adapt it to your purposes:
fun sum [] = 0
| sum (h::t) = h + sum t
