Piratek-(akaDK) How can we find the end of input file? [13] // Problem 1001. Reverse Root 31 Dec 2006 14:17

I think it's easy problem we can use something like
binary search for find answer , but how can we read
input data :
if it will be input.txt we can do like that
while not eof do
but it's now console

You don't need to use binary search
All numbers can be stored in extended type

If so then it's very simple, but i'm getting WA :(
Isn't simple recurse with sqrt() function not right? why?

I obviously can't read the input correctly.
I do it this way:

while not eof do
begin
read(a);
...
end;
...

Is that right?

Yes of course sqrt(), but
trouble is to get numbers from flow
You should read text char by char until eof
Numbers can be stored in array without recursion

I'm stupid :)
It can be solved simple with seekeof
while not seekeof do
...
read(number);
...

Yes,I can't do it too!
It annoyed me for a long time:

1-st "int" is not enough to input
2-nd try to use printf instead setprecision.

Here is your AC program:
But better is to use only array, not stack!!!

And how can I find the end of input using Java? FAQ says nothing about it...

Does it work?
while (in.nextToken() != StreamTokenizer.TT_EOF) {
// ...
}

You can use "seekeof" function instead of "eof". It presented even in BP7.0, so you can easily find description.
