вернуться в форумWould you like to tell me why I got WA using this source code? var tot : array [0..9] of longint; i : byte; zg : longint; n : string; r : longint; error : integer; function cf(ll:byte) : longint; var tt,ti : longint; begin tt := 1; for ti := 1 to ll do tt := tt * 10; cf := tt; end; function change(aa,bb:byte) : longint; var tstr : string; o : longint; begin tstr := copy(n,aa,bb-aa+1); val(tstr,o,error); change := o; end; procedure solve(now:byte); var k : byte; ttt : string; begin str(now,ttt); for k := 1 to length(n) do begin if k = 1 then begin if ttt[1] < n[1] then tot[now] := tot[now] + cf(length(n)- k); if ttt[1] = n[1] then tot[now] := tot[now] + change(2,length (n)) + 1; end; if k = length(n) then begin tot[now] := tot[now] + change(1,k-1); if ttt[1] <= n[k] then inc(tot[now]); end; if (k>1) and (k<length(n)) then begin tot[now] := tot[now] + change(1,k-1) * cf(length(n) - k); if ttt[1] < n[k] then tot[now] := tot[now] + cf(length(n) - k); if ttt[1] = n[k] then tot[now] := tot[now] + change(k+1,length (n))+1; end; end; end; procedure out; begin tot[0] := zg - tot[1] - tot[2] - tot[3] - tot[4] - tot[5] - tot[6] - tot[7] - tot[8] - tot[9]; for i := 0 to 9 do writeln(tot[i]); end; begin readln(n); val(n,r,error); zg := 0; for i := 1 to length(n)-1 do zg := zg + 9 * cf(i-1) * i; zg := zg + length(n) * (r mod cf(length(n))+1-cf(i)); for i := 1 to 9 do solve(i); out; end. |
