Remove First Assignment
Motivation
Experience with equality types (along with more experience writing recursive functions with pattern matching).
Code to Implement
file: | src/main/sml/warm_up_remove_first/remove_first.sml | ![]() |
functions: | remove_first |
remove_first
fun remove_first(xs : ''a list, target : ''a) : ''a list = raise NotYetImplemented
Remove the first item which matches target
if it exists. For example, remove_first([1,2,3,4,5], 3)
should return the list [1,2,4,5]
.
If the target does not exist, return the complete list. For example, remove_first([1,2,3,4,5], 6)
should return the list [1,2,3,4,5]
.
