A quantity named for this symbol is equal to the cycle rank of all N-F-A's with epsilon transitions by Eggan's theorem. That "height" named for this symbol is used to measure the structural complexity of regular expressions. 
A quantity named for this symbol is equal to the cycle rank of all N-F-A's with epsilon transitions by Eggan's theorem. That "height" named for this symbol is used to measure the structural complexity of regular expressions. An operator named for this symbol returns the smallest superset of an alphabet that contains the empty set and that is closed under the string concatenation problem; that unary operation was developed by Stephen (*) Kleene. In Python, using this symbol before the word "args" passes a list of positional arguments into a function. In many languages, block comments begin with a forward slash followed by this symbol, and end with this symbol followed by a forward slash. In C, the operator indicated by this symbol is used to dereference variables. For 10 points, name this symbol used to declare pointers in C, which is sometimes called the asterisk.
