    呵呵
    var
    m,s,t,ti:longint;
    ms:array[1..2,0..300000] of longint;
    ts:array[0..300000] of longint;
    begin
    readln(m,s,t);
    ms[2,0]:=m;
    ts[0]:=0;
    for ti:=1 to t do
    begin
    if ms[2,ti-1] >= 10 then
    begin
    ms[1,ti]:=ms[1,ti-1]+60;
    ms[2,ti]:=ms[2,ti-1]-10;
    end
    else
    begin
    ms[1,ti]:=ms[1,ti-1];
    ms[2,ti]:=ms[2,ti-1]+4;
    end;
    if ts[ti-1]+17 > ms[1,ti] then
    ts[ti]:=ts[ti-1]+17
    else
    ts[ti]:=ms[1,ti];
    if ts[ti] >= s then
    begin
    writeln('Yes');
    writeln(ti);
    halt;
    end;
    //main
    end;
    writeln('No');
    writeln(ts[t]);
    end.

    敢问你for j:=0 to 13 do 的13是哪里来的。。。

      先把10以上的魔法全用光,剩下的魔法值为个位数最大为9,在加上休息一次所得到的4点就是13
