What I must do?? →MOPDOBOPOT← 25 июн 2009 16:17

I'm sorry, but WTF???
My program works correct on sample and all other tests, but I got WA1 ><
Code:

program abcdefgh;

var t1,t2,t3: array[1..100] of longint;
i,k,j,n,time: longint;

begin
read(n);
for i:=1 to n do
readln(t1[i],t2[i],t3[i]);
for i:=1 to n-1 do
for j:=i+1 to n do begin
if t1[i]>t1[j] then begin
                     k:=t1[i]; t1[i]:=t1[j]; t1[j]:=k;
                     k:=t2[i]; t2[i]:=t2[j]; t2[j]:=k;
                     end;
if t3[i]>t3[j] then begin
                     k:=t3[i]; t3[i]:=t3[j]; t3[j]:=k;
                     end;
end;
time:=0;
for i:=1 to n do
if t1[i]<time then inc(time,t2[i]) else
                    time:=t1[i]+t2[i];
if time-t3[1]<0 then writeln(0) else writeln(time-t3[1]);
end.

Easy!

You wrong here:
> if time-t3[1]<0 then writeln(0) else writeln(time-t3[1]);

This way to calculate time is wrong.

Try this:
2
1 2 3
2 3 6
The answer is:
0
Your program output:
3

P.S. The first test is not necessary from statement, it may be more easier test, for exapmle.
