Hello,
Anyone can translate this into being tail recursive
if it's possible:
let rec interval_tree intervals =
match intervals with
[] -> Empty
| _ ->
let x_mid = median intervals in
let left, mid, right = partition intervals x_mid in
let left_list = L.sort leftmost_bound_first mid in
let right_list = L.sort rightmost_bound_first mid in
Node (x_mid,
left_list, right_list,
interval_tree left, interval_tree right)
I'm afraid my program could crash on a very long list of intervals.
Thanks a lot,
F.
