OJ Board

Your Backtracking implementation is a little bad. I used the same algorithm and I also used the next_permutation. But, when I tested your program and mine. The count results that recall the function was like below. input => count result 1 1 1 1 1 => you: 324, me: 121 1 2 3 4 5 => you: 2948, me: 456 ...

Could you give me a tricky sample or advice?
I don't know what's wrong in my code.
Below my code.
Actually, My mistake is not to consider MULTISET input data.

432
423

Test it. Correct Answer is 4.
The missile can move forward.

Edit: Try to update the algorythm so one of the bases is always less than the other one, instead of checking every single case, given the input it is possible to figure out which of the 2 bases is supposed to be the lesser than the other. The OJ defines an ONLINE_JUDGE constant so you don't have to...

I don't know what's problem in my code.
Frankly, I think my algorithm is fast enough. But, I got TLE. I don't know the reason. Who can advice me?
Below my code.

Actually, We don't need to consider about the same number inputs.
The problem defined like below.

... All pancakes in a stack have different diameters. ...

So I made a algorithm based on the problem. and I got A.C.

Frankly, If I input the same numbers in my program, It's crazy..

If your answer is correct, but you had given a TLE from judge. You can use a kind of technic that store your humble numbers in memory. That means precalculate the humble numbers(it's just total 5842). I hope it helps you. ps. anyway, your answer printing is wrong. you have to consider about the numb...

Sample Input 5 3 1 1 E RFRFRFRF 3 2 N FRRFLLFFRRFLL <-- Second Test 0 3 W LLFFFLFLFL <-- Next Test Sample Output 1 1 E 3 3 N LOST 2 3 S Frankly, I think in the second test, old robot will be replaced by new robot at last grid position just soon after the old robot was disappeared. So, I can't under...

Who can explain me about this problem?
I can't understand a sample below.

sample

3 2 N
FRRFLLFFRRFLL

Why the sample's answer is

3 3 N LOST

Could you simulate it?

Thankx, friends~ : )

Who know this problem? I searched articles related with this problem. And I applied some rule that I couldn't be realized from the articles. But, I can't get A.C yet. Who CAN explain what's wrong in my program or logic? Thankx, friends~ #include <iostream> //#include <fstream> #include <string> #inc...

I have tested all sample that I could find below articles. And I have passed the testcases. BUT, online-judge give me W.A(Wrong Answer) Frankly, I believe online-judge. So I think I have a fault in my program. Who can give advice me aboue this? Thankx, your help. : ) #include <string> #include <cstr...

My code is a little long. but, Actually, I have already written my BigInteger class. So, I just want to reuse my class. My program is well-working at VC and G++. However, online-judge give me C.E(compile error). Who know about this problem? Give me your idea, plz... deleted ---- Thankx, bro : )

I don't know what's problem in my code. Who can advice me? (Actually, I have passed many testcase that I found below threads.) I'll appreciate your help. ------------------------------------------------------------------------------ I got A.C Actually, My mistake is if-statement's position. *wrong c...

I got A.C. But, I have just changed my Clear part. I used for-loop to clear array instead of memset function. I can't understand why the memset function occur Runtime error. Who can explain me about it? You define 'day' as an array of bools yet you use sizeof(int) instead of sizeof(bool) when you s...
