Set of operators to use for regular expressions -

c* - zero or more

c+ - one or more

^c - start with a character

c$ - end with a character

a|b - or (multiple conditions)

Use the above operators and create regular expressions

Ex: ^a+b*[c|d]e$ - this expression returns strings starting with a at least once followed by 0 or more occurrence of b and c or d ending with e.
