Find out value of max_int without using the the constant max_int ... Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software [Non-text...
... You can try min_int - 1;; Otherwise you can use shift functions (lsl, lsr, ...) or an arithmetic approach: increase an int until its value decreases....
... let rec find_max x = if x + 1 < x then x else find_max (x + 1) ;; find_max 17 ;; (* have a drink *) Cheers. -- Stefano Zacchiroli -- Master in Computer...
... Or on a binary computer ... let rec find_max x = if x * 2 > x then find_max (x * 2) else x * 2 - 1;; print_string (string_of_int (find_max 1) ^ "\n");; ...
... Why? To me this sounds suspiciously like a homework assignment. max_int is in pervasives, you don't even need to preface with Sys.max_int or Int.max_int...
