LeetCode 341 Flatten Nested List Iterator (DFS) Given a nested list of integers, implement an iterator to flatten it. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Example 2: 题目链接:htt......
In this case, you can see you’re looking for an InvocationExpression that’s a call to Regex.Match, where the ArgumentList has a second Argument node that contains a StringLiteralExpression. If the string value represents an invalid regex pattern, such as “\pXXX,” you’ve found the...
Your class's IEnumerable.GetEnumerator method should call this nonvirtual method, which should return a nested public enumerator struct. Explicitly implement the IEnumerator.Current property on your enumerator struct.For more information about implementing custom collections and about how to implement ...
