I obtained the sample input from the regional site: http://acm.ashland.edu/2005/problem-set.html I've got all test cases correct except for test cases 23-32 (which my output shows more room). Here's what I found in the 23rd test case: (room in (x1, y1), (x2, y2) format) Room 1 : (5542, 5201), (5583,...

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 this is a wrong answer (1.5625 should round up to 1.563). This is crazy! I've got...

Yup I do think that I compiled as optimized code. I'm using Visual Studio 2005 .NET for compiling this BigInteger class. Sometimes, I noticed that by changing some part of the code, I can gain some speed difference (by looping 1000000 times) like 10 seconds, but usually I have to sacrifice it for co...

494 WA till I changed input from string to char array.. Why?

Hey guys, I've tried submitting this code so many times, until I changed the input from string to char array, and it got AC. Here is my code which got WA (it's exactly the same output of the code I got AC, the only difference is input by char array instead of string)... #include <iostream> #include ...
