Given an array A of positive integers, call a (contiguous, not necessarily distinct) subarray of A good if the number of different integers in that subarray is exactly K. (For example, [1,2,3,1,2] has 3different integers: 1, 2, and 3.) Return the n

In my previous article, What is OWIN? A Beginners Guide we learned the basics of OWIN and the benefits it brings to building web application in Asp.Net frameworks. We have also learnt to build a very simple application using Project Katana and different w
