What is the best way of telling whether an element `x` is present in a sorted list `a`?
Using `searchsortedlist`, I also need to check that the element is present
in the list. This is what I do
function isinsortedlist(a, x)
n = searchsortedfirst(a, x)
n <= length(a) && a[n] == x
end
Shouldn't `searchsortedlist` return also a bool to tell whether the element
is already in the list?
Thank you,
