Solution

* (star)Matches the preceding character or subexpression zero or more times
so the answer is :::::::.aaba aa
here start with \"a (or more times ab) a\" both start and end a\'s are single

Matches the preceding character or subexpression one or more times
azbc+,,,azbcbc+,,, here z is (.)

Marks the start and end of a bracket expression.
a01,,,a0a,,,aza here z is (.)

+ Matches the preceding character or subexpression one or more times.
? Matches the preceding character or subexpression zero or one time
| indicates a choice between two or more items.
very good weather

{} Marks the start and end of a quantifier expression.
abc

ababc,,,abc,,,bc,,,abc

azbc,,,azbcbc here z is(.)

\\Marks the next character as a special character, a literal, a backreference, or an octal escape.
