Minimal basics on Regular Expression
This article is for those who have graduated from Computer Science background or have basic knowledge of natural language processing concepts. I will not share any coding stuffs in this post and all basic rules with examples will be posted in next article.
In our graduation time we had one paper called Theory of Automata which dealt with NFA, DFA etc. There we had used some magic/wildcard symbols to complete the expression. Like “^(a|b*)+ababa?cd$”
I know it looks nothing more than a junk to a common man but it does lots of such things which saves our time and effort in real life of programming world. Whatever you saw, was nothing but a small example of regular expression.
