The single-line comment can be described by the regular expression in Lex as follows:

singleLineComment "//"([^ ]*\\[ \t]* )*([^ ]*[^ \t \\][ \t]*|[ \t]*) 

For the concept of the single-line comment, we can express it using five symbols:

 l b w n a 

where l denotes the slash / symbol, b denotes the backslash \ symbol, w denotes a white-space symbol (which is either space or tab), n denotes the newline symbol, and a denotes any symbol other than slash /, backslash \, space, tab, or newline.

You are asked to convert the above regular expression into an NFA using Glushkov construction, followed by the subset construction to give a DFA.
