The ;; token tells the toplevel it has reached the end of an expression. This is never necessary in a full, properly formed OCaml program. Share. WebHashtbl (ハッシュ表)モジュール. Hashtbl モジュールは効率的な変更可能ルックアップテーブルで実装されている。. ハッシュ表を作成するにはこう書く: 123456 は hashtbl の初期サイズだ。. この初期値は単純にハッシュ表に載せるデータ量をうまく予想したものだ ...

WebHashtbl.iter f tbl applies f to all bindings in table tbl. f receives the key as first argument, and the associated value as second argument. Each binding is presented exactly once to f.The order in which the bindings are passed to f is unspecified. However, if the table contains several bindings for the same key, they are passed to f in reverse order of introduction, … WebNov 17, 2016 · I don't understand your description of the hashtable. Is the type of the hashtable (string, int) Hashtbl.t or is it (string, int list) Hashtbl.t?If it's the latter, you can just use Hashtbl.iter or (possibly better) Hashtbl.fold.. If your hashtable is of type (string, int) Hashtbl.t you could perhaps rewrite your code to keep a list of ints instead of an … garfield high school washington
