sum_scan
Write a function
fun sum_scan(xs : int list) : int list
which produces a list whose values are the running totals of the values in xs.
Example [1,2,3,4,5,6,7,8]
For example:
sum_scan([1,2,3,4,5,6,7,8])
would produce:
[1,3,6,10,15,21,28,36]
xs 1 2 3 4 5 6 7 8 sum_scan(xs) 1 3 6 10 15 21 28 36
Example [131,231,425]
For example:
sum_scan([131,231,425])
would produce:
[131, 362, 787]
xs 131 231 425 sum_scan(xs) 131 362 787
