Functions to Use
List Structure
- [] construct an empty list
- :: construct a list out of a head element and a tail list
- null is the passed in list empty?
- hd head element of the passed in list
- tl tail list of the passed in list
Code to Implement
| file: | src/main/sml/warmup_squares_fun/my_length.sml |  |
| functions: | to_squares |
to_squares
A list of integers xs is passed to to_squares. Evaluate to a list where each item is the square of its counterpart in the passed list.
fun to_squares(xs : int list) : int list =
raise Fail "NotYetImplemented"
For example, if the passed list is [1,2,3,4] then to_squares would evaluate to [1, 4, 9, 16].
