130: WA

OK, I briefly gave a description of how this might be solved in the combined 130 / 131 list but since that topic is mostly dominated by 131, I'm creating the new topic. First, let me say that the example data should have been reserved as some of the tricky data. I would have failed with my original ...

Oops! I goofed again. (Sorry!) Actually it looks like your test for Straight Flush only allows for a Royal Straight, not a Royal Flush. A Straight is any sequence of consecutively ranked cards, regardless of suit. Because of how they've defined the hands, an A, 2, 3, 4, 5 would count as a straight, ...

111: WA

OK, first I'm confused by the sample input/output on 111. Sample 1 looks correct. Sample output 2 does not match the sample input. At least assuming that the problem description can be trusted. Here's the 2nd sample input: 10 3 1 2 4 9 5 10 6 8 7 1 2 3 4 5 6 7 8 9 10 4 7 2 3 10 6 9 1 5 8 3 1 2 4 9 5...

I stand corrected. Yes, I would go with the order they used in the introduction. This problem obviously needs review because they call it *poker* but don't follow the rules of *poker*. Back to square one. Strangely, the introduction indicates that an 'A'ce should be considered less than a two, but t...

According to http://www.poker-rulez.com/poker-basics.html, Aces are always high. They can never be considered lower than a 2. Yes, a straight could contain a 2, 3, 4, 5, 6 or 10, J, Q, K, A. But not A, 2, 3, 4, 5. Any series of consecutive numbers can be a straight. But since the Ace is always high,...

As far as problem 130 goes, try this for an idea. Take the input data, start your counting at position 1 with the number of people listed, killing and shifting people as described. When your simulation gets down to one person, determine that person's starting position. Now you want to shift the calc...

I haven't looked through your entire code, but the following snippet seems wrong: case 'A' : hand [0] = 'a' ; break ; case '2' : hand [0] = 'b' ; break ; case '3' : hand [0] = 'c' ; break ; case '4' : hand [0] = 'd' ; break ; case '5' : hand [0] = 'e' ; break ; case '6' : hand [0] = 'f' ; break ; ca...

I think this is your issue: for ( ; i<=j; i++) { if ( hesapla(i+1) > max ) max = hesapla(i+1); } This goes through the loop for every number from i through j, but it calculates the cycle on the i+1 value. So when i = j, it will calculate the cycle for j+1! Change the loop control to only process whi...

I received one direct e-mail saying that there was a student that was supposed to be looking at it. But as yet, (s)he hadn't reported back. They've recognized that there is an issue, but the person assigned to it has not had much progress yet.

In general, its pretty easy to tell whether your code is as good as the first place code. In the problem set listing -- click on the percentage inside the parenthesis for the problem in question. This will provide a ranking of everyone who solved the problem sorted by time spent, memory spent, and d...

Doh! I apologize -- and stand corrected. Now that mine was also rejected with a WA, I closely read the multiple input description and found that I misspoke earlier. It looks like you're handling the multiple input correctly. On the other hand -- I see for the base case (where n = 1), your code inclu...

OK, it's been college since I did any pascal programming. Still, your main routine seems wrong to me. I count three separate readln statements (outside of quotes of course). The problem description is quite clear that the input consists only of a single integer on a line by itself. Once you read tha...

I agree, this is a very easy problem. The description has changed some since I solved this, though. At the time, the trick was that some of the coordinates could be less than 0, but always with an absolute value less than 10000. Even though they now promise positive integers, I would allow for 0 as ...

Sorry, I haven't looked closely at your program to help with the compile error. But I can help on this: The judge doesn't care when you output your data -- as long as your output matches the solution. So you are perfectly free to process each test case and output the answer for each test case before...

But that would kill the fun! No, seriously! That's the whole point of this website -- programming practice. The website gives the problems, with some sample input / output. Meanwhile, the judge withholds the most devious, conniving inputs and outputs. You are tasked with writing programs that not on...
