[10128 - Queue] test case is not correct

Hello. I try to solve this problem, but always got WA. In this problem, if n =1, then l and r should be 1. But I write a program to test this condition, and I got an unanticipated result. Following is my test program: int _t = in.nextInt(); for (int _l = 0; _l < _t; _l++) { int n = in.nextInt(); int...

Re: 11176 - Winning Streak

Hi.
Finally, I was solved this problem.
I was misunderstanding Ivan said, try to calculate the "count" of "from i consecutive games you get no more than j consecutive wins",

Thanks.

These numbers will have at most 100 digits. I consider it means the sum of two values is at most 100 digits at first, but always...

Re: 11176 - Winning Streak

Hello. I am trying to solve this problem. I already used DP to calculate the number of "from i consecutive games you get no more than j consecutive wins", just like Ivan said. But I still confused how to derive the correct answer from this DP table. My biggest problem is, for example i=3 and j=1, th...

Re: 10375 - Choose and Divide

If you are using Java and keep getting WA, you might want to try using C/C++. At first I converted the program in the 1st thread into a Java program. I also took the suggestion in the 2nd thread and converted the 6 loops into a single loop. However that got me WA whether I use Math.log10 or Math.lo...
