## Concatenation
|
|
|
|
Regex : `/^AB%/`
|
|
Psuedo: `str.start str(AB) str.end`
|
|
|
|
Machine:
|
|
```
|
|
->o --A--> o --epsilon--> o --B--> (o)
|
|
|
|
Submachine_A --epsilon--> Submachine_B
|
|
```
|
|
|
|
## Union
|
|
|
|
Regex : `/^A|B$/`
|
|
Psuedo: `str.start glyph(A) | glyph(B) str.end`
|
|
|
|
Machine:
|
|
```
|
|
epsilon--> o --A--> o --epsilon
|
|
/ \
|
|
->o ->(o)
|
|
\ /
|
|
epsilon--> o --B--> o --epsilon
|
|
```

## Kleene Closure
|
|
|
|
Regex : `/^A*$/`
|
|
Psuedo: `str.start glyph(A).repeating str.end`
|
|
|
|
Machine:
|
|
```
