Why is the Single Responsibility Principle important? What is Inversion of Control? How does that relate to dependency injection? How does a 3 tier application differ from a 2 tier one? Show me a portfolio of all the applications you worked on, and tell me how you contributed to design them. What are some alternate ways to store data other than a relational database? Why would you do that, and what are the trade-offs?

1. experiences. 2. a graph related question as follows, later on I found out a tricky solution online. //problem: count islands in a graph // // A graph is a collection of nodes that are connected to each other with // edges. There are N nodes, numbered 1..N. and M edges. Each edge connects // two different node numbers. Here is an example graph with N= 8, M=6: // // 1---2---3 6 8 // | | | // 4---5 7 // // The goal is to count the number of islands in the graph. An island is a // graph of nodes that are connected only to themselves and not to any of the // other nodes in the graph. The above example has three islands. As a node // not connected to anything at all is regarded as it own island. // Implement the function IslandCount() below. The values N and M are passed // in, along with the array E which contains pairs of node numbers that are // connected by edges. The above example has E equal to // // E = { 1,2,2,3, 1,4, 2, 5, 4,5, 6, 7} // // IslandCount() should return the number of islands in the graph.
