In my project, I'm at a point where I need to attach a handful of event listeners to various HTML elements (buttons). A few, in particular, share a parent element, which makes me want to use a delegation event; something like...

I wrote a javascript code for finding the first two consecutive prime numbers (that doesn't have divisors except one and itself) with a specific gap between them. It works well but take too much time to give results for large numbers, when i test:
gap = 8 ,start = 3,000,000 and end = 4,000,00...

This QA site doesn't quite take the form that others do. Here, we have fairly specific questions. But I already see two Project Euler #1 questions that are similar. Are these duplicates?
I have a program that specifies when an alarm should be active (say, 10AM to 8PM). Part of my program then checks if the alarm is active right now. The "is it active" checker needs to deal with alarm ranges that cross the midnight boundary into tomorrow (say, 8PM to 10AM alarm).

First time on this community board. I'm trying to design and develop a singleton class that will handle resolution and configuration of log4j (not log4j2). The basic idea is to have a single class, reusable in any application, that handles log4j configuration and management.
