back to boardWA #1 Posted by Sevala 31 Oct 2009 16:48 My solution program Project2; {$APPTYPE CONSOLE} uses SysUtils; type t2 = array[0..101] of integer; var arr: t2; len, kol, i: integer; s, sa: array[0..501] of string; ss: string; function preobr(st: string): string; var l: integer; i: integer; begin l := Length(st); for i := 1 to l do begin case st[i] of 'i': st[i] := '1'; 'j': st[i] := '1'; //1 'a': st[i] := '2'; 'b': st[i] := '2'; 'c': st[i] := '2'; //2 'd': st[i] := '3'; 'e': st[i] := '3'; 'f': st[i] := '3'; //3 'g': st[i] := '4'; 'h': st[i] := '4'; //4 'k': st[i] := '5'; 'l': st[i] := '5'; //5 'm': st[i] := '6'; 'n': st[i] := '6'; //6 'p': st[i] := '7'; 'r': st[i] := '7'; 's': st[i] := '7'; //7 't': st[i] := '8'; 'u': st[i] := '8'; 'v': st[i] := '8'; //8 'w': st[i] := '9'; 'x': st[i] := '9'; 'y': st[i] := '9'; //9 'o': st[i] := '0'; 'q': st[i] := '0'; 'z': st[i] := '0' //0 else st[i] := '0'; end; end; preobr := st; end; function cmp(ind: Integer; nom: integer): Boolean; var l, j: integer; begin l := Length(s[nom]); if (Len < l + ind - 1) then begin cmp := false; exit; end; for j := 1 to l do begin if ss[ind + j - 1] <> s[nom][j] then begin cmp := False; Exit; end; end; cmp := true; end; function sravn(ind: Integer): t2; var j: integer; be, se: t2; begin if ind >= len + 1 then exit; FillChar(be, 102 * sizeof(integer), 0); FillChar(se, 102 * sizeof(integer), 0); be[0] := 101; for j := 1 to kol do begin if cmp(ind, j) then begin se := sravn(ind + length(s[j])); Inc(Se[0]); if se[0] > 101 then continue; se[se[0]] := j; if se[0] < be[0] then be := se; end; end; sravn := be; end; procedure ps; var i: integer; begin for i := 1 to kol do s[i] := preobr(sa[i]); arr := sravn(1); end; begin while true do begin Readln(ss); len := Length(ss); if ss = '-1' then break; readln(kol); for i := 1 to kol do Readln(sa[i]); ps; if (arr[0] <> 0) and (arr[0] <> 101) then begin for i := arr[0] downto 2 do write(sa[arr[i]], ' '); write(sa[arr[1]]); writeln; end else Writeln('No solution.'); end; end. I don't now, where is my mistake, my program give right answers to my tests. In the procedure ps, program converted strings and solve. In function sravn, I use DP and find right sequence. Take word and compare it with substring. If it do for sting, find best sequence for new substring. Sorry for my poor english. Я не знаю, в чем моя ошибка, все мои тесты программа проходит. В процедуре ps, конвертируются слова, зачем ищется решение с помощью функции sravn. Она возвращает в нулевом элементе количество потребовавшихся слов и сами слова. Используется динамическое программирование. |
