regular expression

The operator ^matches the left end of a line, and $ matches the right end of a line. The operator ^is also used to introduce complemented character classes, but the context always makes it clear which meaning is intended.

For example, ^[^aeiou] *$ matches any complete line that does not contain a lowercase vowel.

a) How do you tell which meaning of A is intended?

b) Can you always replace a regular expression using the A and $ operators

by an equivalent expression that does not use either of these operators?
