Program of the Week 02 - Unique Element
So initially I was planning to do a program on basic object / motion detection from video using opencv. I tried to find my old code for it but was unable to find it. So I thought rather than wasting time finding it, I'd rather find it myself. But since you are reading this long introduction and you probably have read the title by now, that ain't happening; this week at least. So what alternative I have then today, pretty sure there are a ton of programs for finding unique elements from a list or what not, and this one will probably join its ranks as well.

He'd cleared many rounds before and was now in the technical round. The problem given to him was simple: "Given a list of elements, you need to find the non-repeating element from the list.
