vertex array is not required in NFA class (Thompson Construction Algorithm)

[keshav2010]

Why are we creating an array of vertices ? i think we can simply have an int to keep track of number of vertices within a NFA. In case im wrong or missing out something, please do let me know.

How's it going keshav,

This was implemented by our contributor @AlexMathew, but back in 2014. You're more than welcome to update on top of this and contribute an optimized implementation!

Best,
