I'm gonna answer my own question: Yes, it works, I didn't get a TLE.

Hello everyone, could you guys please explain the following: Suppose I don't know how many annagramatic numbers there are and I want to do what the problems asks me to. Since N is less than 10,000,000, and I can input, for example, 8000000, I might need to generate 7! permuations for 1 number. I kno...

Hello guys, please help, I tested all the cases in the problem description, uDebug and this thread, however, I got WA. Here's the code: #include <stdio.h> #include <vector> #include <algorithm> #include <iostream> #include <cmath> using namespace std; typedef vector<int> chamber; int sum_chamber(con...

Hi everyone, I wrote my solution in Java and here's what I did: 1) I worked with StringBuilders. I know that might be not the best option, but I'm a self-taught non-competitive guy who just learns how to code using UVa Judge. 2) The first thing I do is I sort my input string converted to StringBuild...

Hello everyone,

The Java submission guidelines say:

Do not use public classes (even Main must be non public to avoid compile error). However, you can add and instance as many classes as needed.

However, I tried submitting some problems with Main being public and got AC.

Hello everyone, I think that the problem description should be tweaked. It says that ''two computers are interconnected if they are directly connected or if they are interconnected with the same computer". c 1 2 c 2 3 c 3 4 c 4 5 c 5 6 c 6 7 q 1 7 - true, according to the program grader However...

Hello guys, I'm just going to start doing this problem after reading a piece on Union Find in Algorithms by R. Sedgewick. Unlike you all, I would like to do it in Java. Knowing that input/output might be a pain, I'd like to ask you what the multiple input problem is. I found here and there that it i...
