Oh, heck; let's do this the short way: 100 is the closest multiple of 5 below 101, and 100 ÷ 5 = 20, so there are twenty multiples of 5 between 1 and 101.

But wait: 25 is 5×5, so each multiple of 25 has an extra factor of 5 that I need to account for. How many multiples of 25 are between 1 and 101? Since 100 ÷ 25 = 4, there are four multiples of 25 between 1 and 101.

There are 4 buckets of coins. Real coins weigh one gram each. fake grams
weigh 2 grams each. Each bucket is fake (contains only fake coins) or real
(contains only real coins). You have weighing machine, which can be used
only one weighing. If there are 9 coins per bucket, how can you determine
all the buckets that are fake with just one weighing.

Given a binary tree, you need to verify it is a binary search tree or not.
How do you do that?

Write a C function, which takes a number n and positions p1 and p2 and
returns if the the bits at positions p1 and p2 are same or not.

Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet address range for the resulting subnet network and a subnet bitmap.

For classless supernetting, please use the CIDR Calculator. For classful supernetting, please use the IP Supernet Calculator. For simple ACL (Access Control List) wildcard mask calculations, please use the ACL Wildcard Mask Calculator.

A Java EE application may contain one or more Java EE components such as EJBs, Web modules, resource adapters, or J2EE application client modules. Each Java EE component can have an associated deployment descriptor -- an XML file that describes the component. Java enterprise components are deployed using the Java Archive (JAR) file format, which branches into additional formats to handle various component types.

The Java Archive (JAR) file format is based on the ZIP file format and enables you to bundle multiple Java EE components into a single file. A JAR file can contain Java class files, XML descriptor files, auxiliary resources, static HTML files, and other files associated with each Java EE component. A standard Java Web application is deployed in a Web Application Archive (WAR) file, which is a JAR file with the extension of .war. A standard Java EE application is deployed in an Enterprise Application Archive (EAR) file, which is a JAR file with an extension of .ear.

A WAR file is a specialized JAR file containing Web application components such as servlets, JSP files, HTML files, deployment descriptors, utility JAR files, etc. A WAR file can be deployed to a Web server such as Tomcat.

Up until this year, if you created applications with a combination of Java servlets, JSPs (JavaServer Pages), JMS (Java Message Service) components and EJBs (Enterprise JavaBeans), you had very few inexpensive production deployment alternatives. While you could test your applications on evaluation copies of commercial servers such as IBM WebSphere, BEA Weblogic, SUN Java System Application Server, or the Oracle Application Server; production deployment on these servers could be very costly for small enterprises, or those with budgetary constraints. The only feasible alternative was the open source JBoss server. In 2005, this landscape changed in a dramatic way with the advent of the freely available, open source Apache Geronimo server.

This article tells you what you need to know about the Geronimo server, and guides you towards a rapid start working with the server. It provides an opportunity to install and run the server, then deploy a complete enterprise application.

Before you ask: what is Geronimo?
