Grammar taken from [https://www.cs.utexas.edu/users/novak/grammar.html]
There is one change from the grammar above and that is that all statement in begin end must end with a ;. This is true for if, while also. I believe that I could let ; parsing to be parsed as spaces(optional) but I decided to follow grammar.
