Code to Implement

file: src/main/sml/warmup_squares_fun/to_squares.sml Smlnj-logo.png
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].
