Re: 11407 - Squares

Omg I have read previous posts and now all I can say is WTF :roll: ! DP...BFS...etc why make this so complicated? First of all, n should be always 4 or less for every N in the range (1-10000). You can try to prove this (I did, believe me it's not so hard). Just use a boolean array and 4 nested loops...

Sure thing, avoid doubles at all cost. You get Wrong Answer just because of precision error. You don't even add eps, no wonder you got Wrong asnwer.

Re: 10226 - Hardwood Species

@Imti his output is correct. I am afraid you overlooked an extra space. Just use a structure, sort and binary search. And remember to print a blank line between cases. There are no extra blanks or extra spaces or anything...just take the inputs with gets() and handle doubles carefully. by sazzadcsed...

Re: 10374 - Election

F*** this stupid problem. Not only the input contains leading and trailing spaces, there can be "futile" blank lines throughout the judge data which must be ignored in order to get Accepted. The judge data is SHIT...I request the admins to fix this. This kind of problem teaches you nothing but only ...

Re: 11609 - Teams

It's easy to derive this summation formula...after deriving this, why don't you write down all the values of this summation from n = 1 to n = 7 on paper? May be you will notice a pattern. If you do notice a pattern may be you will understand why and how such a pattern exists. Good luck.

Re: 846 - Steps

There is a simpler solution regardless of n being odd/even. First notice that the result only depends on the value of |x - y| regardless of the values of x and y. Now try a few cases with pen and paper and you will soon find out why a formula can be derived using sqrt(|x - y|). Hint: (n * n) = ((n -...

Guess what I did the same mistake at first. It was only when I finished coding tried the input 5 cs. and got the output czq or sth and I realized I was actually doing it WRONG because I didn't read the problem statement carefully. You did the same mistake. You have to convert the ciphertext back to ...

Ok this problem is really very annoying....a couple of tips if you are struggling to get Accepted. This is very important...whatever you do don't use doubles or power functions. I even tried creating my own power functions which always returns integer value(I got accepted with this in other problems...

Re: 11292 - Dragon of Loowater

Damn the input contains negative numbers...beware....I got 4 Wrong Answers because of this. Although I think this is very illogical as n = number of heads and m = number of knights so n and m can't be less than 0. Nevertheless, not all problems should seem to be logical I guess.
