啊艹，熟悉的fpc，让我想起了lazarus和刚入坑OI学pascal的时候
~~我戏真多~~

@[s_TDY](/user/322535) 您死循环了吧

```pascal
for i:=2 to n do if y[i]<y[j] then j:=i;
```
这句改成
```pascal
for i:=2 to n do if(y[i]<y[j])and(a+b>=x[i]) then j:=i;
```

这是我帮您全部改好后的代码
```pascal
program p1478;
var x,y:array[0..5000] of integer;
n,s,a,b,i,j,app:integer;
begin
readln(n,s);
readln(a,b);
for i:=1 to n do readln(x[i],y[i]);
app:=0;
y[0]:=32767;
while s>=0 do
begin
j:=0;
for i:=1 to n do if(y[i]<y[j])and(a+b>=x[i])then j:=i;
if s-y[j]>=0 then
begin
s:=s-y[j];
app:=app+1;
y[j]:=32767;
end
else break;
end;
write(app);
end.
```
