Difference between * and + regex
regex
Solution
Each of them are quantifiers, the star quantifier(`*`) means that the preceding expression can match zero or more times it is like `{0,}` while the plus quantifier(`+`) indicate that the preceding expression MUST match at least one time or multiple times and it is the same as `{1,}` .
So to recap :
a* ---> a{0,} ---> Match a or aa or aaaaa or an empty string
a+ ---> a{1,} ---> Match a or aa or aaaa but not a string empty
Problem
Can anybody tell me the difference between the `*` and `+` operators in the example below: `[<>]+` `[<>]*`
