Check if item is in a list (Lisp)
Common Lisp FIND is not a good idea: > (find nil ‘(nil nil)) NIL Above would mean that NIL is not in the list (NIL NIL) – which is wrong. The purpose of FIND is not to check for membership, but to find an element, which satisfies a test (in the above example the test … Read more
SwiftUI dynamic List with Sections does not Layout correctly
Giving List a set of items seems to make it incorrectly treat Section as a single view. You should probably file a radar for this, but in the meantime, this will give you the behavior you’re looking for: struct ListView : View { let mygroups = [ TestData(title: “Numbers”, items: [“1″,”2″,”3”]), TestData(title: “Letters”, items: [“A”,”B”,”C”]), … Read more
Removing duplicates from a list in Haskell without elem
Both your code and nub have O(N^2) complexity. You can improve the complexity to O(N log N) and avoid using elem by sorting, grouping, and taking only the first element of each group. Conceptually, rmdups :: (Ord a) => [a] -> [a] rmdups = map head . group . sort Suppose you start with the … Read more
In Dart, what’s the difference between List.from and .of, and between Map.from and .of?
The important difference between the from and of methods are that the latter have type annotations and the former do not. Since Dart generics are reified and Dart 2 is strongly typed, this is key to both ensuring the List/Map is correctly constructed: List<String> foo = new List.from(<int>[1, 2, 3]); // okay until runtime. List<String> … Read more
Iterate over pairs in a list (circular fashion) in Python
def pairs(lst): i = iter(lst) first = prev = item = i.next() for item in i: yield prev, item prev = item yield item, first Works on any non-empty sequence, no indexing required.
How to append to a list in Terraform?
You can use the concat function for this. Expanding upon the example in your question: variable “foo” { type = “list” default = [ 1,2,3 ] } # assume a value of 4 of type number is the additional value to be appended resource “bar_type” “bar” { bar_field = “${concat(var.foo, [4])}” } which appends to … Read more
Finding index of element in a list in Haskell?
How to find the index of the maximum element? How about trying all indexes and checking whether they are the maximum? ghci> let maxIndex xs = head $ filter ((== maximum xs) . (xs !!)) [0..] But this sounds like something for which a function already exists. My code will be more readable, maintainable, and … Read more
