Going through my PE programs and I have PE for this problem as well.
Using C++/STL, I thought that maybe setw in combination with string could be a problem but the following gives PE too:

struct Solution {
string number;

friend ostream& operator<<(ostream& strm, const Solution& solution) {
if ...

Hmmm,

My program just got accepted but gives a different output on this test input. (Please note that there is an error in your test input, it says that there will be 6 more lines of input. This will include the 0, not sure if that is what you meant).
My output is as follows:

Case 1 ...

Hi,

The problem was more challenging than I thought :-).
Basically, I read testcases and output the resulting XML.
For every testcase I first determine the possible relationships between tables (assuming that primary keys can consist of one or more columns), I collect the root nodes (the nodes to ...

Hi,

I also got a WA first, read this post changed my solution and got accepted.
Now the funny part is that I checked all possibilities and got the same result, except for n = 6.
My solution gave first 2^-6 = 1.563e-2 and got a WA.
Now it returns 2^-6 = 1.562e-2 and it gets accepted. In my opinion ...

Hi,

It has been a while so I had to search for things :-).

First I build up a collection of all possible edges.
For every edge I will add the corresponding word to the collection of words for the tail of the edge.
For every word in the collection, remove it (after storing if length >= 3) and for ...

1
WHERE 2 3
FROM I
ORDER S
1 XXX
2 YYY
3 ZZZ
SELECT FROM, ORDER
FROM WHERE
WHERE FROM = 2 AND ORDER = 3 OR 0 = 1

Imho, according to the problem description, the column ORDER should be compared to a string constant instead of to a number:
WHERE FROM = 2 AND ORDER = "3" OR 0 = 1

You are ...

Just my 2 cents:

After reading this thread I decided to give it try (very tempting with its 0% solutions) and just started with a program that just reads input (not that trivial).
Anyway, if I would find an error in the input the program would hang itself and that is exactly what I got (TLE) which ...

Mmmm, run diff to check for differences but couldn't find any. Guess I am missing something but what?
As it seems that both our programs generate the same output, I assume it has something to do with special cases but I am completely blank. Do you have any ideas?
Thanks,

Hi,

I am getting WA for problem 487 (Boggle Blitz).
Not sure if it depends on reading the input incorrectly or just computing wrong results.
Anyway, here is my test input and test output (other examples would be appreciated as well).
