2009年9月28日 · @mehaase ++ and -- don't exist in c "as syntactic sugar for pointer arithmetic", they exist because many processors have automatic increment and decrement memory access mechanisms (in general pointer indexing, stack indexing) as part of their native instruction set.

If you want your iterator to be a bidirectional iterator you’ll need to provide the necessary information to find the last node of the tree in the iterator returned by end().

2012年8月21日 · OK, if you revert it then I won't edit-war. However, no standard algorithm will wind an iterator back prior to the start point of the range it has been instructed to operate on, so although --end might be valid for some empty input ranges, the algorithm won't perform it and so it isn't required to be valid.
